CVE-2026-63907

A flaw was found in the uiopcigenericsva module of the Linux kernel. This vulnerability, a double free, occurs because memory allocated with devmkzalloc is automatically freed, but the kfreeudev function is also explicitly called during both error handling and device removal. A local attacker cou...

CVE-2026-45868

CVE-2026-45868 affects the Linux kernel pinctrl: single subsystem (pcs_add_gpio_func). The of_parse_phandle_with_args() path increments a device_node refcount and loops through phandles without releasing it, causing a refcount leak. The fix adds of_node_put() to release the reference after extrac...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: soc: bcm: Check for a NULL return from devmkzalloc. As a potential failure during allocation, devmkzalloc may return NULL. Then, pd-pmb and the subsequent lines of code may lead to a null pointer dereferencing. Therefore, it is...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: clk: mmp: pxa1908-apbc – Fixed the issue where NULL values were returned instead of an ISERR error. The devmkzalloc function now returns NULL when an error occurs, rather than error pointers. The check has been corrected...
