In the Linux kernel, the following vulnerability has been resolved: net/sched: actskbmod: Skip non-Ethernet packets Currently, tcfskbmodact assumes that packets use Ethernet as their L2 protocol. This assumption is not always true. For example, for CAN devices: bash $ ip link add dev vcan0 type...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: hwmon: mlxreg-fan Returns a non-zero value when the fan’s current state is enforced from sysfs. The minimum fan speed can be enforced from sysfs. For example, setting the current fan speed to 20 is used to force the fan speed ...

Astra Linux – Vulnerability found in Linux 5.15, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: EDAC/qcom: Do not pass llccdrivdata as edacdevicectlinfo’s pvtinfo. The memory for llccdrivdata is allocated by the LLCC driver. However, when it is passed as private driver information to the EDAC core, it will be freed during t...

In the Linux kernel, the following vulnerability has been resolved: PCI: Avoid deadlock in sriovnumvfsstore caused by pcidevlock The sysfs sriovnumvfsstore path acquires the device lock before the config space access lock: sriovnumvfsstore devicelock A 1 acquires the device lock sriovconfigure...

Astra Linux – Vulnerability in Linux

A issue was discovered in the Linux kernel through version 5.11.10. In the drivers/net/ethernet/freescale/gianfar.c file of the Freescale Gianfar Ethernet driver, it was found that a negative fragment size can be calculated in situations where an rx queue overrun occurs when jumbo packets are use...

In the Linux kernel, the following vulnerabilities have been resolved: Wifi: ath9k: Fixed a potential array-index-out-of-bounds read in ath9khtctxstatus. The bug occurs when txs-cnt—data from a URB provided by a USB device—is larger than the size of the array txs-txstatus, which is HTCMAXTXSTATUS...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: spmi: mediatek – Fixed UAF issue when removing devices The pmif driver data containing the clocks is allocated together with spmicontroller. When a device is removed, spmicontroller is freed first, and then the devices, including...

Astra Linux – Vulnerability in Linux 5.10, Linux

The Linux kernel before version 5.17.2 mishandles seccomp permissions. The PTRACESEIZE code path allows attackers to bypass the intended restrictions on setting the PTSUSPENDSECCOMP flag...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: RISCV: Kernel mappings of the EFI page table must be synchronized before switching to the EFI page table. The EFI page table is initially created as a copy of the kernel page table. When VMAPSTACK is enabled, kernel stacks are...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: RDMA/mlx5: Fixed the issue with mlx5ibgethwstats when used for devices. Currently, when mlx5ibgethwstats is used for a device where portnum = 0, there is a special handling to ensure that the correct counters are used. However,...

Astra Linux – Vulnerabilities in Linux, Linux-6.1, Linux-5.15

In the Linux kernel, the following vulnerability has been resolved: Wifi: wfx: Fixed a possible NULL pointer dereferencing in wfxsetmfpap. Since 'ieee80211beaconget' may return NULL, wfxsetmfpap should check the return value before examining the skb data. Therefore, the latter function should...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net: dpaa2-eth: fix use-after-free in dpaa2ethremove Access to netdev after freenetdev will cause a use-after-free bug. Move the debug log before the freenetdev call to avoid this issue...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: Watchdog: Fixed a possible use-after-free in wdtstartup. The remove path of this module calls deltimer.
