Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/msm/a6xx: Fixed the issue where kvzalloc was used instead of statekcalloc. The adrenoshowobject function is problematic. It reallocates the pointer it passes on during the first call, when the data is encoded as ascii85. This...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: ASoC: sma1307: Added a NULL check in sma1307settingloaded. All variables allocated by kzalloc and devmkzalloc could potentially be NULL. Multiple pointer checks and their cleanup procedures have been added. This issue was...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: Wifi: brcm80211 – Handle PMKOp allocation failure The kzalloc function in brcmfpmksav3op will return null if physical memory runs out. As a result, if we dereference the null value, a null pointer dereference bug will occur. Retu...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: The block operation involving GFPNOIO around the sysfs-store function. The sysfs-store function is called with the queue frozen. Meanwhile, there are several -store callbacks such as updatenrrequests, wbt, scheduler that use...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: clk: mmp: pxa1908-mpmu: Fixed the issue where a NULL value was returned instead of an ISERR error pointer. The devmkzalloc function now returns NULL if there is an error, rather than error pointers. The check has been updated to...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: xfs: removed calls to xchkxfiledescr macros. The xchkxfiledescr macros use kasprintf, which may fail to allocate memory if the formatted string is longer than 16 bytes or whatever value nofail currently guarantees. Some of the...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: crypto: caam – fix DMA corruption on long hmac keys When a key longer than the block size is provided, it is copied and then hashed into the actual key. The memory allocated for the copy needs to be rounded to the DMA cache...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/xe/migrate: prevents infinite recursion. If the buf + offset is not aligned to XECAHELINEBYTES, we fall back to using a bounce buffer. However, the bounce buffer is allocated on the stack, and the only alignment requirement...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: Bluetooth: btusb: Fixed a potential NULL dereferencing on a kmalloc failure. Avoid potential NULL pointer dereferences by checking the return value of kmalloc and properly handling allocation failures...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: LoongArch: Fixed missing NULL checks for kstrdup 1. Replaced “offindnodebypath"/"” with “ofroot” to avoid multiple calls to “ofnodeput”. 2. Fixed a potential kernel error during early boot when memory allocation fails while...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: hwmon: cgbc-hwmon Add a NULL check after devmkzalloc The driver allocates memory for sensor data using devmkzalloc, but did not check whether the allocation succeeded. In the event of a memory allocation failure, dereferencing th...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: skmsg: The allocskmsg function can be called from a non-sleepable context. The skpsockverdictrecv function uses rcureadlock protection. We need the callers to pass a gfpt argument to avoid issues. The report from syzbot stated:...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: kunit: The executor component has a memory leak that occurs during failures in kunitfiltertests. It is possible that memory allocation for the “filtered” data may fail, but the copy operation of the suite may still succeed. In th...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: btrfs: The free pages operation fails with an error in btrfsuringreadextent. In this function, the pages object is never freed, with the hope that it will be picked up by btrfsuringreadfinished whenever that function is executed ...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: ntfs: -dcompare must not block. … So don’t use getname there. Switch it to kmallocPATHMAX, GFPNOWAIT. Yes, ntfsdhash can almost certainly handle smaller allocations, but let the ntfs team deal with that—keep the allocation siz...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: Networking: DSA: Felix: Fixed possible NULL pointer dereferencing. As a possible failure during allocation, kzalloc may return a NULL pointer. Therefore, it is better to check for ‘sgi’ to prevent the dereferencing of a NULL...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/buddy: Fixed the error handling code for allocrange. A few users have reported display corruption when booting the machine into KDE Plasma or playing games. We have identified a problem where, whenever allocrange failed to fi...
