CVE-2026-89553

A use-after-free vulnerability exists in the Linux kernel's nouveau/gem driver. In the non-uvmm path, a race condition between the info ioctl's VMA lookup and the GEM close path can close the VMA before the lookup completes. This allows a local attacker with low privileges to potentially achieve ...

CVE-2026-89553 nouveau/gem: reserve the bo in the info ioctl around the vma lookup

In the Linux kernel, the following vulnerability has been resolved: nouveau/gem: reserve the bo in the info ioctl around the vma lookup In the non-uvmm path, there could be a race between the info lookup finding the vma, and the gem close path closing the vma leading to a use-after-free. Spotted...

CVE-2026-89540

A race condition in the Linux kernel's sunrpc component allows a local attacker to trigger concurrent access to set_gssp_clnt(). The root cause is that create_use_gss_proxy_proc_entry() publishes /proc/net/rpc/use-gss-proxy via proc_create_data() before the gssp_lock mutex is initialized, creatin...
