Threats tagged 'usn-9020-1'

It was discovered that the io_uring subsystem in the Linux kernel contained a memory leak when handling certain asynchronous commands. A local attacker could possibly use this to cause a denial of service (memory exhaustion). (CVE-2026-80811) It was discovered that the io_uring subsystem in the Linux kernel did not properly validate the size of certain query requests. A local attacker could possibly use this to cause a denial of service (system hang). (CVE-2026-81009) It was discovered that the io_uring subsystem in the Linux kernel did not properly handle canceled task work when processing certain wait operations, leading to the operation being performed in the wrong task context. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2026-81010) It was discovered that the io_uring subsystem in the Linux kernel did not properly track buffer consumption when receiving truncated network messages. A remote attacker could possibly use this to corrupt the receive buffers of certain applications, resulting in a denial of service or another unspecified impact. (CVE-2026-97618) Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.
