Astra Linux – Vulnerability in Linux 5.15

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

CVE-2026-72123

A use-after-free flaw was found in the Linux kernel's CAN BCM Broadcast Manager subsystem. During RX operation teardown, a concurrent receive handler can race and re-arm the throttle timer after the operation has been scheduled for deallocation. When the deallocation completes, the timer is still...

CVE-2026-72121

A flaw was found in the Linux kernel's Controller Area Network CAN Broadcom bcm driver. A race condition exists when the driver attempts to update filter and timer values simultaneously with ongoing receive operations. This can lead to the transmission of stale CAN reply frames with an incorrect...

CVE-2026-72114

A flaw was found in the Linux kernel's Controller Area Network CAN Broadcom bcm driver. This vulnerability arises from insufficient validation of frame lengths when processing Remote Transmission Request RTR replies. An attacker could exploit this by sending a specially crafted RTR reply, which m...
