{"id":"USN-8462-1","summary":"linux-oracle-5.15 vulnerabilities","details":"\nIt was discovered that the Linux kernel algif_aead module did not properly\nhandle in-place cryptographic operations. This flaw is known as Copy Fail.\nA local attacker could use this to escalate privileges, or possibly escape\na container. (CVE-2026-31431)\n\nIt was discovered that the Linux kernel did not properly handle shared page\nfragments during socket buffer operations, collectively known as Dirty\nFrag. A logic flaw existed in the XFRM ESP-in-TCP subsystem and in the\nRxRPC networking subsystem when processing paged fragments. A local\nattacker could use this to escalate privileges, or possibly escape a\ncontainer. (CVE-2026-43284, CVE-2026-43500)\n\nIt was discovered that a logic flaw existed in the XFRM ESP-in-TCP\nsubsystem in the Linux kernel when handling socket buffer fragments. This\nflaw is known as Fragnesia. A local attacker could use this to escalate\nprivileges, or possibly escape a container. (CVE-2026-43503,\nCVE-2026-46300)\n\nQualys discovered that a race condition existed in the ptrace subsystem of\nthe Linux kernel when privileged processes are exiting. An unprivileged\nlocal attacker could use this issue to expose sensitive information.\n(CVE-2026-46333)\n\nSeveral security issues were discovered in the Linux kernel.\nAn attacker could possibly use these to compromise the system.\nThis update corrects flaws in the following subsystems:\n  - Cryptographic API;\n  - Ethernet bonding driver;\n  - Packet sockets;\n  - RDS protocol;\n  - TLS protocol;\n(CVE-2026-31419, CVE-2026-31504, CVE-2026-31533, CVE-2026-43033,\nCVE-2026-43077, CVE-2026-43078, CVE-2026-43494,
