Vulnerability id: CVE-2020-29661
[3.10.0-957.12.2.vz7.96.21 to 3.10.0-1127.8.2.vz7.158.8] Incorrect locking in TTY subsystem could lead to use-after-free conditions and cause memory corruption.
Vulnerability id: PSBM-122990
[3.10.0-957.12.2.vz7.96.21 to 3.10.0-1127.8.2.vz7.158.8] โBad unlock balanceโ error in ipmr_mfc_seq_stop(). It was discovered that the implementation of IPv6 multicast routing could try to access wrong data when a user tried to read certain files in /proc. An attacker could exploit that from a container to trigger โbad unlock balanceโ error in ipmr_mfc_seq_stop(), followed by a kernel crash.
Vulnerability id: PSBM-122991
[3.10.0-957.12.2.vz7.96.21 to 3.10.0-1127.8.2.vz7.158.8] Soft lockup in ext4_ext_find_extent(). It was discovered that certain ioctl operations in ext4 did not check their arguments properly. An attacker could exploit that from a container to trigger soft lockups in ext4_ext_find_extent() function, which could result in a denial of service.
