LSN-0079-1: Kernel Live Patch Security Notice It was discovered that the eBPF implementation in the Linux kernel did not properly track bounds information for 32 bit registers when performing div and mod operations. A local attacker could use this to possibly execute arbitrary code.(CVE-2021-3600) It was discovered that the virtual file system implementation in the Linux kernel contained an unsigned to signed integer conversion error. A local attacker could use this to cause a denial of service (system crash) or execute arbitrary code.(CVE-2021-33909) Source: LSN-0079-1: Kernel Live Patch Security Notice

USN-5021-1: curl vulnerabilities Harry Sintonen and Tomas Hoger discovered that curl incorrectly handled TELNET connections when the -t option was used on the command line. Uninitialized data possibly containing sensitive information could be sent to the remote server, contrary to expectations. (CVE-2021-22898, CVE-2021-22925) Harry Sintonen discovered that curl incorrectly reused connections in the connection pool. This could result in curl reusing the wrong connections.
