UBUNTU-CVE-2022-49888

In the Linux kernel, the following vulnerability has been resolved: arm64: entry: avoid kprobe recursion The cortexa76erratum1463225debughandler function is called when handling debug exceptions and synchronous exceptions from BRK instructions, and so is called when a probed function executes. If...

CVE-2022-49891

CVE-2022-49891 concerns a Linux kernel memory-leak in tracing/kprobe handling. The root cause is that test_gen_kprobe_cmd() frees buf only on the fail path, causing a leak when no failure occurs; the patch moves kfree(buf) from the fail path to the common path, and applies the same fix to test_ge...
