CVSS v3.1 |
| In the Linux kernel, the following vulnerability has been resolved:
tcp: Fix data-races around sysctl_tcp_l3mdev_accept.
While reading sysctl_tcp_l3mdev_accept, it can be changed concurrently.
Thus, we need to add READ_ONCE() to its readers. |
| In the Linux kernel, the following vulnerability has been resolved:
tcp: Fix data-races around sysctl_tcp_base_mss.
While reading sysctl_tcp_base_mss, it can be changed concurrently.
Thus, we need to add READ_ONCE() to its readers. |
| In the Linux kernel, the following vulnerability has been resolved:
tcp: Fix a data-race around sysctl_tcp_mtu_probe_floor.
While reading sysctl_tcp_mtu_probe_floor, it can be changed concurrently.
Thus, we need to add READ_ONCE() to its reader. |
| In the Linux kernel, the following vulnerability has been resolved:
tcp: Fix data-races around sysctl_tcp_migrate_req.
While reading sysctl_tcp_migrate_req, it can be changed concurrently.
Thus, we need to add READ_ONCE() to its readers. |
| In the Linux kernel, the following vulnerability has been resolved:
tcp: Fix a data-race around sysctl_tcp_notsent_lowat.
While reading sysctl_tcp_notsent_lowat, it can be changed concurrently.
Thus, we need to add READ_ONCE() to its reader. |
| In the Linux kernel, the following vulnerability has been resolved:
ipv4: Fix a data-race around sysctl_fib_multipath_use_neigh.
While reading sysctl_fib_multipath_use_neigh, it can be changed
concurrently. Thus, we need to add READ_ONCE() to its reader. |
| In the Linux kernel, the following vulnerability has been resolved:
ipv4: Fix data-races around sysctl_fib_multipath_hash_policy.
While reading sysctl_fib_multipath_hash_policy, it can be changed
concurrently. Thus, we need to add READ_ONCE() to its readers. |
| In the Linux kernel, the following vulnerability has been resolved:
ip: Fix data-races around sysctl_ip_prot_sock.
sysctl_ip_prot_sock is accessed concurrently, and there is always a chance
of data-race. So, all readers and writers need some basic protection to
avoid load/store-tearing. |
| In the Linux kernel, the following vulnerability has been resolved:
udp: Fix a data-race around sysctl_udp_l3mdev_accept.
While reading sysctl_udp_l3mdev_accept, it can be changed concurrently.
Thus, we need to add READ_ONCE() to its reader. |
| In the Linux kernel, the following vulnerability has been resolved:
ipv4: Fix data-races around sysctl_fib_multipath_hash_fields.
While reading sysctl_fib_multipath_hash_fields, it can be changed
concurrently. Thus, we need to add READ_ONCE() to its readers. |
| In the Linux kernel, the following vulnerability has been resolved:
tcp: Fix a data-race around sysctl_tcp_thin_linear_timeouts.
While reading sysctl_tcp_thin_linear_timeouts, it can be changed
concurrently. Thus, we need to add READ_ONCE() to its reader. |
| In the Linux kernel, the following vulnerability has been resolved:
tcp: Fix data-races around sysctl_tcp_recovery.
While reading sysctl_tcp_recovery, it can be changed concurrently.
Thus, we need to add READ_ONCE() to its readers. |
| In the Linux kernel, the following vulnerability has been resolved:
tcp: Fix a data-race around sysctl_tcp_early_retrans.
While reading sysctl_tcp_early_retrans, it can be changed concurrently.
Thus, we need to add READ_ONCE() to its reader. |
| In the Linux kernel, the following vulnerability has been resolved:
tcp: Fix data-races around sysctl_tcp_slow_start_after_idle.
While reading sysctl_tcp_slow_start_after_idle, it can be changed
concurrently. Thus, we need to add READ_ONCE() to its readers. |
| In the Linux kernel, the following vulnerability has been resolved:
tcp: Fix data-races around sysctl_tcp_max_reordering.
While reading sysctl_tcp_max_reordering, it can be changed
concurrently. Thus, we need to add READ_ONCE() to its readers. |
| In the Linux kernel, the following vulnerability has been resolved:
gpio: gpio-xilinx: Fix integer overflow
Current implementation is not able to configure more than 32 pins
due to incorrect data type. So type casting with unsigned long
to avoid it. |
| In the Linux kernel, the following vulnerability has been resolved:
spi: bcm2835: bcm2835_spi_handle_err(): fix NULL pointer deref for non DMA transfers
In case a IRQ based transfer times out the bcm2835_spi_handle_err()
function is called. Since commit 1513ceee70f2 ("spi: bcm2835: Drop
dma_pending flag") the TX and RX DMA transfers are unconditionally
canceled, leading to NULL pointer derefs if ctlr->dma_tx or
ctlr->dma_rx are not set.
Fix the NULL pointer deref by checking that ctlr->dma_tx and
ctlr->dma_rx are valid pointers before accessing them. |
| In the Linux kernel, the following vulnerability has been resolved:
KVM: Don't null dereference ops->destroy
A KVM device cleanup happens in either of two callbacks:
1) destroy() which is called when the VM is being destroyed;
2) release() which is called when a device fd is closed.
Most KVM devices use 1) but Book3s's interrupt controller KVM devices
(XICS, XIVE, XIVE-native) use 2) as they need to close and reopen during
the machine execution. The error handling in kvm_ioctl_create_device()
assumes destroy() is always defined which leads to NULL dereference as
discovered by Syzkaller.
This adds a checks for destroy!=NULL and adds a missing release().
This is not changing kvm_destroy_devices() as devices with defined
release() should have been removed from the KVM devices list by then. |
| In the Linux kernel, the following vulnerability has been resolved:
crypto: qat - fix memory leak in RSA
When an RSA key represented in form 2 (as defined in PKCS #1 V2.1) is
used, some components of the private key persist even after the TFM is
released.
Replace the explicit calls to free the buffers in qat_rsa_exit_tfm()
with a call to qat_rsa_clear_ctx() which frees all buffers referenced in
the TFM context. |

usb: isp1760: Fix out-of-bounds array access
Running the driver through kasan gives an interesting splat:
BUG: KASAN: global-out-of-bounds in isp1760_register+0x180/0x70c
Read of size 20 at addr f1db2e64 by task swapper/0/1
(...)
isp1760_register from isp1760_plat_probe+0x1d8/0x220
(...)
This happens because the loop reading the regmap fields for the
different ISP1760 variants look like this:
for (i = 0; i < HC_FIELD_MAX; i++) { ... }
Meaning it expects the arrays to be at least HC_FIELD_MAX - 1 long.
However the arrays isp1760_hc_reg_fields[], isp1763_hc_reg_fields[],
isp1763_hc_volatile_ranges[] and isp1763_dc_volatile_ranges[] are
dynamically sized during compilation.
Fix this by putting an empty assignment to the [HC_FIELD_MAX]
and [DC_FIELD_MAX] array member at the end of each array.
This will make the array one member longer than it needs to be,
but avoids the risk of overwriting whatever is inside
[HC_FIELD_MAX - 1] and is simple and intuitive to read. Also
add comments explaining what is going on. |
