Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: shmem: Use ramfskillsb for the killsb method of ramfs-based tmpfs. Since ramfs-based tmpfs uses ramfsinitfscontext for the initfscontext method, which allocates fc-sfsinfo, using ramfskillsb allows for its freeing and avoids a...

CVE-2023-53391

CVE-2023-53391 patches the Linux kernel shmem:ramfs-based tmpfs memory leak by replacing kill_sb with ramfs_kill_sb() in ramfs-based tmpfs, freeing fc->s_fs_info during init_fs_context() cleanup. Affected: Linux kernel ramfs/tmpfs shmem path; root cause: memory leak in kill_sb/init_fs_context ...

The vulnerability of the erofs_kill_sb() function in the EROFS file system, a enhanced read-only file system, in the Linux operating system, allows a malicious actor to trigger a service failure.

The vulnerability of the erofskillsb function in the fs/erofs/super.c file of the EROFS file system’s kernel for Linux operating systems is related to the release of previously unallocated memory. Exploiting this vulnerability could allow an attacker to trigger a service failure...
