CVE-2026-43249 9p/xen: protect xen_9pfs_front_free against concurrent calls

In the Linux kernel, the following vulnerability has been resolved: 9p/xen: protect xen9pfsfrontfree against concurrent calls The xenwatch thread can race with other back-end change notifications and call xen9pfsfrontfree twice, hitting the observed general protection fault due to a double-free...

CVE-2026-43249

The CVE-2026-43249 entry describes a race in the Linux kernel 9p/xen frontend: xenwatch and backend change notifications can concurrently call xen_9pfs_front_free, causing a double-free and a general protection fault. The fixes guard the teardown path so only a single caller releases the front-en...

CVE-2026-43230

The CVE-2026-43230 issue affects the Linux kernel’s Reliable Datagram Sockets (RDS) by not clearing the reconnect-pending bit when canceling the reconnect worker before it has been scheduled. This can cause the system to believe a reconnect is pending indefinitely, potentially impairing network o...

CVE-2026-43226

In the Linux kernel, the following vulnerability has been resolved: net/rds: No shortcut out of RDSCONNERROR RDS connections carry a state "rdsconnpath::cpstate" and transitions from one state to another and are conditional upon an expected state: "rdsconnpathtransition." There is one exception t...

CVE-2026-43226

The CVE-2026-43226 issue affects the Linux kernel Reliable Datagram Sockets (RDS). A state-machine bug allowed an RDS_CONN_ERROR to bypass the proper shutdown path via a shortcut through RDS_CONN_CONNECTING, created by RDS/TCP multipath changes. This could leave a connection stuck in shutdown-que...

CVE-2026-43203

The CVE covers a Linux kernel fore200e ATM driver use-after-free during device removal (PCA-200E/SBA-200E). Vulnerability arises when tx_tasklet/rx_tasklet run or pending after fore200e is freed, risking access to freed memory. The published fixes synchronize tasklets with device shutdown by addi...
