A vulnerability was discovered in the Linux kernel in versions prior to v5.14-rc1. Missing size validations on inbound SCTP packets may allow the kernel to read uninitialized memory...

Astra Linux - уязвимость в linux, linux-5.10

A NULL pointer dereference flaw was discovered in the btrfsrmdevice function in fs/btrfs/volumes.c within the Linux Kernel. Triggering this bug requires CAPSYSADMIN. This flaw allows a local attacker to crash the system or leak kernel internal information. The greatest threat posed by this...

Astra Linux - уязвимость в linux, linux-5.10

A memory overflow vulnerability was discovered in the ipc functionality of the memcg subsystem in the Linux kernel. This vulnerability occurs when a user calls the semget function multiple times, thereby creating semaphores. This flaw allows a local user to deplete resources, resulting in a denia...

Astra Linux - уязвимость в linux-5.10

A flaw in the Linux kernel’s implementation of the RDMA communication manager listener code allowed an attacker with local access to set up a socket to listen on a high port. This allowed for a memory element to be used after it was freed. With the ability to execute code, a local attacker could...
