Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: KEYS: Trusted – Fixed a memory leak in tpm2loadcmd. tpm2loadcmd allocates a temporary blob indirectly through tpm2keydecode, but the blob is not freed during failure paths. This issue can be addressed by wrapping the blob with a...

kernel: Linux kernel: Denial of Service due to memory leak in tpm2_load_cmd

A flaw was found in the Linux kernel's trusted keys subsystem. A local user could exploit a memory leak in the tpm2loadcmd function, which fails to free a temporary memory allocation in certain error scenarios. This memory leak could lead to a system-wide Denial of Service DoS by exhausting...

The vulnerability of the tpm2_load_cmd() function in the security/keys/trusted-keys/trusted_tpm2.c module of the Linux kernel’s key management component allows a attacker to trigger a service failure.

The vulnerability of the tpm2loadcmd function in the security/keys/trusted-keys/trustedtpm2.c module of the Linux kernel’s key management component is related to improper memory release memory leak. Exploiting this vulnerability could allow an attacker to trigger a service failure...
