Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: Bluetooth: hcisync: Fixed a double-free in ‘hcidiscoveryfilterclear’. The function ‘hcidiscoveryfilterclear’ frees the ‘uuids’ array and then sets it to NULL. There is a small chance that the following races will occur:...

CVE-2026-74509

A flaw was found in the Linux kernel's Bluetooth subsystem. Specifically, the hcisync component, which manages Bluetooth advertising data, is susceptible to a Use-After-Free UAF vulnerability. This occurs when a pointer to advertising data becomes invalid but is still accessed, particularly durin...

CVE-2026-74528

A flaw was found in the Linux kernel's Bluetooth subsystem. This vulnerability, a use-after-free, occurs when the hcisync component improperly handles connection references, leading to the potential reuse and access of freed memory pointers. A remote attacker could exploit this to cause system...
