Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: EDAC/mc: Fixed the error path ordering in edacmcalloc. When the mci-pvtinfo allocation in edacmcalloc fails, the error path will call putdevice, which will ultimately call the device’s release function. However, the initializatio...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: iio: Buffer: Fixed error handling related to files in IIOBUFFERGETFDIOCTL. If we fail to copy the newly created file descriptor to userland, we try to clean it up by returning the ‘fd’ and freeing the ‘ib’. The code uses...

In the Linux kernel, the following vulnerability has been resolved: schedext: The crash that occurred during the creation of helper kthreads due to scxenable has been fixed. A crash was observed when the schedext selftest runner was terminated with Ctrl+\ while test 15 was running: NIP...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: dmaengine: xilinx: xdma: Fixed error handling for regmap init. The devmregmapinitmmio function now returns ERRPTR upon an error, instead of NULL. The error check has also been fixed, and the error message has been corrected. T...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: net: lan966x: Fixed a potential nullptrderef in lan966xstatsinit. lan966xstatsinit calls createsinglethreadworkqueue, without checking the return value. This may result in NULL being returned. A nullptrderef could occur:...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: ext4: Error checking was added to ext4extreplaysetiblocks. If the call to ext4mapblocks fails due to a corrupted file system, ext4extreplaysetiblocks may get stuck in an infinite loop. This issue can be reproduced by running...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: net/mlx5: HWS, fixed the issue where complex rule rehash operations failed. Moving rules from one matcher to another should not fail. However, if it does fail due to various reasons, the error handling mechanism should allow t...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: drm/tegra: rgb: Fixed the missing clkput in the error handling code for tegradcrgbprobe. If the call to clkgetsys..., "plld2out0" fails, the call to clkgetsys must be undone. Added the missing clkput function and a new label...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: ASoC: da7219: Fixed an error handling path in da7219registerdaiclks. If clkhwregister fails, the corresponding clk should not be unregistered. To handle errors from loops, partial iterations should be cleaned up before performing...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: hfs/hfsplus: Avoid using WARNON for sanity checks; instead, use proper error handling. The commit 55d1cbbbb29e “hfs/hfsplus: Use WARNON for sanity checks” fixed a build warning by converting a comment into a WARNON call...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: btrfs: The BUG function call has been removed after failing to insert a delayed directory index entry. Instead of calling BUG when we fail to insert a delayed directory index entry into the delayed node’s tree, we can simply...
