Red Hat Security Advisory 2021-1739-01 - The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Issues addressed include denial of service, integer overflow, null pointer, out of bounds read, out of bounds write, and use-after-free vulnerabilities.
31fce1366e86f02b959cd930b533a51fadb3cb331be2abae116fa24736734f3eRed Hat Security Advisory 2021-1578-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. Issues addressed include denial of service, integer overflow, memory leak, null pointer, out of bounds read, out of bounds write, and use-after-free vulnerabilities.
0b297866a632113c376963bf7d56d126ab8d48aba795a17aa0f66bba161b11eeUbuntu Security Notice 4752-1 - Daniele Antonioli, Nils Ole Tippenhauer, and Kasper Rasmussen discovered that legacy pairing and secure-connections pairing authentication in the Bluetooth protocol could allow an unauthenticated user to complete authentication without pairing credentials via adjacent access. A physically proximate attacker could use this to impersonate a previously paired Bluetooth device. Jay Shin discovered that the ext4 file system implementation in the Linux kernel did not properly handle directory access with broken indexing, leading to an out-of-bounds read vulnerability. A local attacker could use this to cause a denial of service. Various other issues were also addressed.

10fd709ec5317c6e9ff836aba241b2b37ab6793d5400a1db991201fa616e3608Ubuntu Security Notice 4660-2 - USN-4660-1 fixed vulnerabilities in the Linux kernel. Unfortunately, that update introduced a regression in the software raid10 driver when used with fstrim that could lead to data corruption. This update fixes the problem. It was discovered that a race condition existed in the perf subsystem of the Linux kernel, leading to a use-after-free vulnerability. An attacker with access to the perf subsystem could use this to cause a denial of service or possibly execute arbitrary code. Various other issues were also addressed.

Unfortunately, that update introduced a regression in the software raid10 driver when used with fstrim that could lead to data corruption. This update fixes the problem. It was discovered that a race condition existed in the binder IPC implementation in the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Various other issues were also addressed.

An attacker with access to the perf subsystem could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that the frame buffer implementation in the Linux kernel did not properly handle some edge cases in software scrollback. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Various other issues were also addressed.
