Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: ath10k: Error handling in ath10ksetupmsaresources has been fixed. The devicenode pointer is returned by ofparsephandle, with the refcount incremented. We should use ofnodeput on it after that operation. This function only calls...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: drm/logicvc: A reference leak of the device node occurred in the logicvcdrmconfigParse function. The logicvcdrmconfigParse function calls ogetchildbyname to find the “layers” node, but fails to release the reference, resulting in...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: fbdev: In of: displaytiming, there is a fix for the refcount leak in ofgetdisplaytimings. The function ofparsephandle returns a devicenode with the refcount incremented. This value is stored in ‘entry’ and then copied to...

CVE-2026-80750

In the Linux kernel, the following vulnerability has been resolved: pmdomain: mediatek: fix remaining %pOF after ofnodeput scpsysgetbusprotectionlegacy looks up several legacy bus protection regmaps from device-tree nodes. Two error paths put the device node before checking whether the regmap...

CVE-2026-80750

CVE-2026-80750 is a use-after-free in the Linux kernel's pmdomain: mediatek driver, specifically in scpsys_get_bus_protection_legacy(). Two error paths call of_node_put() before verifying the regmap lookup succeeded, then pass the potentially freed device node to dev_err_probe() with the %pOF spe...

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: drm/tegra: dsi: Added a check for the return value of offinddevicebynode. Added a check on the return value of offinddevicebynode, and return an error if it fails, in order to avoid dereferencing a NULL pointer...

kbd: Local privilege escalation in openvt via incorrect process owner verification allowing passwordless root login

openvt -u is intended to identify the owner of the current VT and then execute login as that user from a privileged context. In the documented kbrequest/init usage, the ownership test in authenticateuser relies on stat"/proc//fd/0". stat on /proc//fd/0 follows the symlink to the underlying TTY...

AZL-95985 CVE-2026-47766 affecting package crun 1.24-6

crun is an open source OCI Container Runtime fully written in C. Prior to version 1.28, crun's default device setup opens the container rootfs /dev directory without ONOFOLLOW. If an OCI bundle contains rootfs/dev as a symlink and the bundle configuration does not mount /dev, crun follows that...

CVE-2026-64154

The flaw is in the Linux kernel's Adreno GPU driver (a6xx_gpu_init), where of_parse_phandle() acquires a device node reference that early error returns fail to release via of_node_put(), causing resource accumulation. The fix uses __free(device_node) for automatic cleanup. Red Hat notes it is not...
