CVE-2026-52950 drm/xe/dma-buf: fix UAF with retry loop

In the Linux kernel, the following vulnerability has been resolved: drm/xe/dma-buf: fix UAF with retry loop Retry doesn't work here, since bo will be freed on error, leading to UAF. However, now that we do the alloc & init before the attach, we can now combine this as one unit and have the init d...

CVE-2026-52922

A flaw was found in the Linux kernel's batman-adv Better Approach To Mobile Ad-hoc Networking module. This vulnerability occurs because the batadvdatforwarddata function fails to validate the success of a memory allocation operation. An attacker could exploit this by triggering a scenario where t...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: APEI/GHES: Ensure that the allocated CPER value will not exceed the limit. The logic in ghesnew prevents allocating too large records by checking whether they are larger than GHESESTATUSMAXSIZE currently 64KB. However, the...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerabilities have been resolved: dmaengine: ti: dma-crossbar: fixed a device leak during am335x route allocation. Make sure to remove the reference used when accessing the crossbar platform device during am335x route allocation...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: drm/xe: Set numsyncs to a limit to prevent excessively large allocations. The exec and vmbind ioctls allow userspace to specify an arbitrary value for numsyncs. Without bounds checking, a very large value of numsyncs can result i...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: gfs2: Prevent recursive memory reclamation The new inode function returns a new inode with inode-imapping-gfpmask set to GFPHIGHUSERMOVABLE. This value includes the GFPFS flag, allowing allocations in that address space to...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: irqchip/mchp-eic: The error code in mchpeicdomainalloc has been fixed. If irqdomaintranslatetwocell sets “hwirq” to = MCHPEICNIRQ 2, it may lead to an out-of-bounds access. The code checks for invalid values, but does not set the...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: ASoC: SOF: ipc4-topology: Corrected the allocation size for bytes controls. The size of the data behind scontrol-ipccontroldata for bytes controls is as follows: 1 sizeofstruct sofipc4controldata + // kernel-only struct 2...
