CVE-2022-1473

Summary: CVE-2022-1473 concerns a bug in the OPENSSL_LH_flush() function in OpenSSL 3.0 that breaks reuse of memory for removed hash table entries, used when decoding certificates or keys, leading to unbounded memory growth and potential DoS in long-lived processes (e.g., TLS clients/servers). Wh...

CVE-2020-35508

CVE-2020-35508 is a Linux kernel issue describing a race condition and incorrect initialization of the child/parent process ID handling when filtering signal handlers. The flaw permits a local attacker to bypass checks and send signals to a privileged process. Multiple Nessus/MiracleLinux Unity a...

CVE-2019-18805

CVE-2019-18805 affects the Linux kernel prior to 5.0.11. A signed integer overflow occurs in net/ipv4/sysctl_net_ipv4.c and in tcp_input.c (tcp_ack_update_rtt()) when a very large value is written to /proc/sys/net/ipv4/tcp_min_rtt_wlen, potentially causing a denial of service or other impact. Con...

CVE-2019-19816

CVE-2019-19816 affects the Linux kernel 5.0.21: mounting a crafted btrfs image can trigger a slab-out-of-bounds write in __btrfs_map_block in fs/btrfs/volumes.c due to mishandling of the data stripes value = 1. The connected Nessus advisory blocks (Unity Linux UTSA-2026-004332 and related plugin ...

CVE-2020-8832

The CVE-2020-8832 entry concerns the Ubuntu 18.04 LTS Linux kernel where the fix for CVE-2019-14615 (clearing data structures on context switches for certain Intel graphics processors) was incomplete.
