CVE-2026-99203
In the Linux kernel, the following vulnerability has been resolved: pipe: preserve existing fasync readers on writer setup failure FSETFL and FIOASYNC decide whether to invoke -fasync before pipefasync takes pipe-mutex. Two enables of one ORDWR FIFO can therefore both enter the callback...

The Linux kernel contains a vulnerability in the pipe subsystem where a slab-use-after-free occurs during send_sigio() under memory pressure. The root cause is located in pipe_fasync(): when two enables of one O_RDWR FIFO occur, a second enable can update a reader entry but fail the writer entry ...
