| CVE-2026-23262 | 1 Linux | 1 Linux Kernel | 2026-05-26 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: gve: Fix stats report corruption on queue count change The driver and the NIC share a region in memory for stats reporting. The NIC calculates its offset into this region based on the total size of the stats region and the size of the NIC's stats. When the number of queues is changed, the driver's stats region is resized. If the queue count is increased, the NIC can write past the end of the allocated stats region, causing memory corruption. If the queue count is decreased, there is a gap between the driver and NIC stats, leading to incorrect stats reporting. This change fixes the issue by allocating stats region with maximum size, and the offset calculation for NIC stats is changed to match with the calculation of the NIC. | ||||
| CVE-2026-46300 | 1 Linux | 2 Kernel, Linux Kernel | 2026-05-26 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: net: skbuff: preserve shared-frag marker during coalescing skb_try_coalesce() can attach paged frags from @from to @to. If @from has SKBFL_SHARED_FRAG set, the resulting @to skb can contain the same externally-owned or page-cache-backed frags, but the shared-frag marker is currently lost. That breaks the invariant relied on by later in-place writers. In particular, ESP input checks skb_has_shared_frag() before deciding whether an uncloned nonlinear skb can skip skb_cow_data(). If TCP receive coalescing has moved shared frags into an unmarked skb, ESP can see skb_has_shared_frag() as false and decrypt in place over page-cache backed frags. Propagate SKBFL_SHARED_FRAG when skb_try_coalesce() transfers paged frags. The tailroom copy path does not need the marker because it copies bytes into @to's linear data rather than transferring frag descriptors. | ||||
| CVE-2026-43391 | 1 Linux | 1 Linux Kernel | 2026-05-26 | 8.8 High |
| In the Linux kernel, the following vulnerability has been resolved: nsfs: tighten permission checks for handle opening Even privileged services should not necessarily be able to see other privileged service's namespaces so they can't leak information to each other. Use may_see_all_namespaces() helper that centralizes this policy until the nstree adapts. | ||||
| CVE-2026-23453 | 1 Linux | 1 Linux Kernel | 2026-05-26 | 7.5 High |
| In the Linux kernel, the following vulnerability has been resolved: net: ti: icssg-prueth: Fix memory leak in XDP_DROP for non-zero-copy mode Page recycling was removed from the XDP_DROP path in emac_run_xdp() to avoid conflicts with AF_XDP zero-copy mode, which uses xsk_buff_free() instead. However, this causes a memory leak when running XDP programs that drop packets in non-zero-copy mode (standard page pool mode). The pages are never returned to the page pool, leading to OOM conditions. Fix this by handling cleanup in the caller, emac_rx_packet(). When emac_run_xdp() returns ICSSG_XDP_CONSUMED for XDP_DROP, the caller now recycles the page back to the page pool. The zero-copy path, emac_rx_packet_zc() already handles cleanup correctly with xsk_buff_free(). | ||||
| CVE-2026-23455 | 1 Linux | 1 Linux Kernel | 2026-05-26 | 9.1 Critical |
| In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_conntrack_h323: check for zero length in DecodeQ931() In DecodeQ931(), the UserUserIE code path reads a 16-bit length from the packet, then decrements it by 1 to skip the protocol discriminator byte before passing it to DecodeH323_UserInformation(). If the encoded length is 0, the decrement wraps to -1, which is then passed as a large value to the decoder, leading to an out-of-bounds read. Add a check to ensure len is positive after the decrement. | ||||
| CVE-2026-23456 | 1 Linux | 1 Linux Kernel | 2026-05-26 | 8.2 High |
| In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_conntrack_h323: fix OOB read in decode_int() CONS case In decode_int(), the CONS case calls get_bits(bs, 2) to read a length value, then calls get_uint(bs, len) without checking that len bytes remain in the buffer. The existing boundary check only validates the 2 bits for get_bits(), not the subsequent 1-4 bytes that get_uint() reads. This allows a malformed H.323/RAS packet to cause a 1-4 byte slab-out-of-bounds read. Add a boundary check for len bytes after get_bits() and before get_uint(). | ||||
| CVE-2026-23457 | 1 Linux | 1 Linux Kernel | 2026-05-26 | 8.6 High |
| In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_conntrack_sip: fix Content-Length u32 truncation in sip_help_tcp() sip_help_tcp() parses the SIP Content-Length header with simple_strtoul(), which returns unsigned long, but stores the result in unsigned int clen. On 64-bit systems, values exceeding UINT_MAX are silently truncated before computing the SIP message boundary. For example, Content-Length 4294967328 (2^32 + 32) is truncated to 32, causing the parser to miscalculate where the current message ends. The loop then treats trailing data in the TCP segment as a second SIP message and processes it through the SDP parser. Fix this by changing clen to unsigned long to match the return type of simple_strtoul(), and reject Content-Length values that exceed the remaining TCP payload length. | ||||
| CVE-2026-23458 | 1 Linux | 1 Linux Kernel | 2026-05-26 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: netfilter: ctnetlink: fix use-after-free in ctnetlink_dump_exp_ct() ctnetlink_dump_exp_ct() stores a conntrack pointer in cb->data for the netlink dump callback ctnetlink_exp_ct_dump_table(), but drops the conntrack reference immediately after netlink_dump_start(). When the dump spans multiple rounds, the second recvmsg() triggers the dump callback which dereferences the now-freed conntrack via nfct_help(ct), leading to a use-after-free on ct->ext. The bug is that the netlink_dump_control has no .start or .done callbacks to manage the conntrack reference across dump rounds. Other dump functions in the same file (e.g. ctnetlink_get_conntrack) properly use .start/.done callbacks for this purpose. Fix this by adding .start and .done callbacks that hold and release the conntrack reference for the duration of the dump, and move the nfct_help() call after the cb->args[0] early-return check in the dump callback to avoid dereferencing ct->ext unnecessarily.

| CVE-2026-23459 | 1 Linux | 1 Linux Kernel | 2026-05-26 | 8.2 High |
| In the Linux kernel, the following vulnerability has been resolved: ip_tunnel: adapt iptunnel_xmit_stats() to NETDEV_PCPU_STAT_DSTATS Blamed commits forgot that vxlan/geneve use udp_tunnel[6]_xmit_skb() which call iptunnel_xmit_stats(). iptunnel_xmit_stats() was assuming tunnels were only using NETDEV_PCPU_STAT_TSTATS. @syncp offset in pcpu_sw_netstats and pcpu_dstats is different. 32bit kernels would either have corruptions or freezes if the syncp sequence was overwritten. This patch also moves pcpu_stat_type closer to dev->{t,d}stats to avoid a potential cache line miss since iptunnel_xmit_stats() needs to read it. | ||||
| CVE-2026-31392 | 1 Linux | 1 Linux Kernel | 2026-05-26 | 8.1 High |
| In the Linux kernel, the following vulnerability has been resolved: smb: client: fix krb5 mount with username option Customer reported that some of their krb5 mounts were failing against a single server as the client was trying to mount the shares with wrong credentials. It turned out the client was reusing SMB session from first mount to try mounting the other shares, even though a different username= option had been specified to the other mounts. By using username mount option along with sec=krb5 to search for principals from keytab is supported by cifs.upcall(8) since cifs-utils-4.8. So fix this by matching username mount option in match_session() even with Kerberos. For example, the second mount below should fail with -ENOKEY as there is no 'foobar' principal in keytab (/etc/krb5.keytab). The client ends up reusing SMB session from first mount to perform the second one, which is wrong. ``` $ ktutil ktutil: add_entry -password -p testuser -k 1 -e aes256-cts Password for testuser@ZELDA.TEST: ktutil: write_kt /etc/krb5.keytab ktutil: quit $ klist -ke Keytab name: FILE:/etc/krb5.keytab KVNO Principal ---- ---------------------------------------------------------------- 1 testuser@ZELDA.TEST (aes256-cts-hmac-sha1-96) $ mount.cifs //w22-root2/scratch /mnt/1 -o sec=krb5,username=testuser $ mount.cifs //w22-root2/scratch /mnt/2 -o sec=krb5,username=foobar $ mount -t cifs | grep -Po 'username=\K\w+' testuser testuser ``` | ||||
| CVE-2026-31393 | 1 Linux | 1 Linux Kernel | 2026-05-26 | 8.1 High |
| In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: Validate L2CAP_INFO_RSP payload length before access l2cap_information_rsp() checks that cmd_len covers the fixed l2cap_info_rsp header (type + result, 4 bytes) but then reads rsp->data without verifying that the payload is present: - L2CAP_IT_FEAT_MASK calls get_unaligned_le32(rsp->data), which reads 4 bytes past the header (needs cmd_len >= 8). - L2CAP_IT_FIXED_CHAN reads rsp->data[0], 1 byte past the header (needs cmd_len >= 5). A truncated L2CAP_INFO_RSP with result == L2CAP_IR_SUCCESS triggers an out-of-bounds read of adjacent skb data. Guard each data access with the required payload length check. If the payload is too short, skip the read and let the state machine complete with safe defaults (feat_mask and remote_fixed_chan remain zero from kzalloc), so the info timer cleanup and l2cap_conn_start() still run and the connection is not stalled. | ||||

| CVE-2026-22190 | 2 Cmu, Panda3d | 2 Panda3d, Panda3d | 2026-05-26 | 7.5 High |
| The egg-mkfont utility in Panda3D versions up to and including 1.10.16 contains an uncontrolled format string vulnerability. The -gp (glyph pattern) command-line option is used directly as the format string for sprintf() with only a single argument supplied. If an attacker provides additional format specifiers, egg-mkfont may read unintended stack values and write the formatted output into generated .egg and .png files, resulting in disclosure of stack-resident memory and pointer values. | ||||
| CVE-2026-22189 | 2 Cmu, Panda3d | 2 Panda3d, Panda3d | 2026-05-26 | 9.8 Critical |
| The egg-mkfont utility in Panda3D versions up to and including 1.10.16 contains a stack-based buffer overflow vulnerability due to use of an unbounded sprintf() call with attacker-controlled input. When constructing glyph filenames, egg-mkfont formats a user-supplied glyph pattern (-gp) into a fixed-size stack buffer without length validation. Supplying an excessively long glyph pattern string can overflow the stack buffer, resulting in memory corruption and a deterministic crash. Depending on build configuration and execution environment, the overflow may also be exploitable for arbitrary code execution. | ||||
| CVE-2026-22188 | 2 Cmu, Panda3d | 2 Panda3d, Panda3d | 2026-05-26 | 5.5 Medium |
| The deploy-stub component in Panda3D versions up to and including 1.10.16 contains a denial of service vulnerability due to unbounded stack allocation. The deploy-stub executable allocates argv_copy and argv_copy2 using alloca() based directly on the attacker-controlled argc value without validation. Supplying a large number of command-line arguments can exhaust stack space and propagate uninitialized stack memory into Python interpreter initialization, resulting in a reliable crash and undefined behavior. | ||||
