Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: fbdev: The issue was fixed by correcting fbsetvar to prevent a null-ptr dereference in fbvideomodetovar. If fbaddvideomode in fbsetvar fails to allocate memory for fbvideomode, it may lead to a null-ptr dereference in...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: btrfs: fixed an issue where an uninitialized pointer was freed during the readalloconename function. The readalloconename function does not initialize the name field of the passed fscryptstr structure if kmalloc fails to allocate...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: nouveau/dmem: Handling of allocation failures by kcalloc In nouveaudmemevictchunk, if the physical memory runs out, kcalloc will return null. As a result, if we dereference srcpfns, dstpfns, or dmaaddrs, null pointer...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ASoC: imx-card: Added a NULL check in imxcardprobe The devmkasprintf function returns NULL when memory allocation fails. Currently, imxcardprobe does not check for this case, which results in a NULL pointer being dereferenced. A...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: clk: zynq – Prevent null pointer dereferencing caused by kmalloc failures The kmalloc function in zynqclksetup will return null if physical memory runs out. As a result, if we use snprintf to write data to a null address, a null...

Astra Linux – Vulnerability in Harfbuzz

HarfBuzz is a text shaping engine. Prior to version 12.3.0, there was a null pointer dereference vulnerability in the SubtableUnicodesCache::create function located in src/hb-ot-cmap-table.hh. The function fails to check whether hbmalloc returns NULL before using placement new to construct an...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: Issue: unittest – Fix null pointer dereferencing in ofunittestfindnodebyname Description: When kmalloc fails to allocate memory in kasprintf, name or fullname will be NULL, and strcmp will cause a null pointer dereference...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: xfrm: Update ipcompscratches with NULL when freed Currently, if ipcompallocscratches fails to allocate memory, ipcompscratches holds an obsolete address. Therefore, when we try to free the percpu scratches using...

Astra Linux – Vulnerability in glibc

NSCD: The NetGroup Cache may terminate the daemon due to a memory allocation failure. The NetGroup Cache Daemon’s NSCD netgroup cache uses xmalloc or xrealloc, and these functions may terminate the process due to a memory allocation failure, resulting in a denial of service for clients. This flaw...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ext4: fixed a potential memory leak in ext4fcrecordregions. Since krealloc may return NULL, in this case, ‘state-fcregions’ may not be freed by krealloc. However, ‘state-fcregions’ is already set to NULL. This could lead to a...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: xprtrdma: Decrementing rereceiving on early exit paths In cases where rpcrdmapostrecvs fails to create a work request due to memory allocation failures, for example or exits early, we should decrement ep-rereceiving before...

CVE-2026-89534

A flaw was found in the Linux kernel's svcrdma module. This vulnerability occurs when the system attempts to handle an RDMA Remote Direct Memory Access address change, and a critical memory allocation fails. This can lead to a 'use-after-free' error, where the system tries to access memory that h...

DEBIAN-CVE-2026-89602

In the Linux kernel, the following vulnerability has been resolved: erofs: skip sufficiently large global buffers when resizing zerofsgbufnrpages is advanced only after every global buffer has been grown. If a resize fails after some buffers were enlarged, a retry revisits those enlarged buffers...

CVE-2026-89618

In the Linux kernel, the following vulnerability has been resolved: eventfs: Initialize ei-children and ei-list in initei eventfscreatedir allocates the eventfsinode and initializes it with initei. But this does not initialize the eventfsinode listheads. If the eventfscreatedir fails due to memor...

SUSE CVE-2026-72252

In the Linux kernel, the following vulnerability has been resolved: netfilter: nftsetpipapo: don't leak bad clone into future transaction On memory allocation failure the cloned nftpipapomatch can enter a bad state: - some fields can have their lookup tables resized while others did not - bits...

CVE-2026-80616: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: ieee802154: Avoid calling WARNON on -ENOMEM in cfg802154switchnetns It's pointless to call WARNON in case of an allocation failure in devchangenetnamespace and devicerename, since it only leads to useless splats caused by...

CVE-2026-74728

A flaw was found in the Linux kernel's XFS filesystem. When the system attempts to allocate memory for an XFS buffer and that allocation fails, the xfsbuffree function is called with a null buffer address. This leads to a null pointer dereference, causing the kernel to crash. This vulnerability c...

CVE-2026-74728

CVE-2026-74728 is a NULL pointer dereference in the Linux kernel's XFS filesystem repair tooling. When xfs_buf_alloc_backing_mem() fails, xfs_buf_free() is called with bp->b_addr still NULL. The code then falls through to the folio_put path, which calls virt_to_folio(NULL), dereferencing an in...

CVE-2026-72252

A flaw was found in the Linux kernel. A memory allocation failure during network filter operations can lead to an inconsistent state within the netfilter: nftsetpipapo module. This inconsistency can result in out-of-bounds writes, which may allow a local attacker to cause a system crash denial of...
