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...

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...

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-2026-74728

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...

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: clk: bcm: rpi: A NULL check has been added in raspberrypiclkregister. devmkasprintf returns NULL when memory allocation fails. Currently, raspberrypiclkregister does not check for this case, which results in a NULL pointer being...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: dma-buf: Fixed NULL pointer dereferencing in sanitycheck. If mockchain returns NULL due to a memory allocation failure, it is passed to dmafenceenableswsignaling, resulting in a NULL pointer dereferencing there. Call...

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, variables like name or fullname will be NULL. In this case, strcmp will cause a null...

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 – 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 mbedtls

In Mbed TLS versions prior to 2.28.10 and 3.x before 3.6.3, in some cases of failed memory allocation or hardware errors, uninitialized stack memory was used to construct the TLS Finished message. This could potentially lead to authentication bypasses, such as replay attacks...

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 in ffmpeg5

A flaw was discovered in FFmpeg’s ALS audio decoder, where it does not properly check for memory allocation failures. This can cause the application to crash when processing certain malformed audio files. While it does not lead to data theft or system control, it can be used to disrupt services a...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: clk: zynq – Prevent null pointer dereferencing caused by kmalloc failure 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, the null...

Astra Linux – Vulnerability in libstb

STBVorbis is a single-file library licensed under MIT, designed for processing OGG Vorbis files. A properly crafted file may cause a memory allocation failure in the startdecoder function. In such cases, the function returns early; f-commentlist is set to NULL, but f-commentlistlength is not rese...

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...

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: imxfb: Check fbaddvideomode to prevent nullptrderef. The fbaddvideomode function may fail with -ENOMEM if its internal kmalloc function cannot allocate a struct fbmodelist. In such cases, the modelist remains empty, but th...

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...
