CVE-2026-53550

A flaw was found in js-yaml, a JavaScript YAML parser and dumper. A remote attacker can exploit this vulnerability by providing a specially crafted YAML document that repeatedly uses the same alias in a merge sequence. This can lead to algorithmic CPU exhaustion, causing the Node.js worker or eve...

CVE-2026-53243

A flaw was found in the Linux kernel. An uninitialized stack variable in the rseqexituserupdate function can lead to an information leak. This occurs due to an indeterminate sequencing of expressions during the initialization of the rseqids structure, where ids.nodeid is assigned using an...

CVE-2026-53180

A flaw was found in the Linux kernel's timer migration handling. An incorrect assumption in the tmigrhandleremotecpu function regarding local softirq path handling of CPU timers can lead to a livelock. This occurs when a timer expires after the local timer wheel advances but before remote handlin...
