UBUNTU-CVE-2022-50234
In the Linux kernel, the following vulnerability has been resolved: iouring/afunix: defer registered files gc to iouring release Instead of putting iouring's registered files in unixgc we want it to be done by iouring itself. The trick here is to consider iouring registered files for cycle...
CVE-2022-50234 io_uring/af_unix: defer registered files gc to io_uring release

CVE-2022-50234
CVE-2022-50234 concerns the Linux kernel’s io_uring/af_unix subsystem. The vulnerability arises from deferring the garbage-collection of registered files to the io_uring release path rather than performing it via unix_gc(), coupled with using these registered files for cycle-detection without act...
Linux kernel 安全漏洞
Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in Linux kernel that stems from not properly handling garbage collection of iouring registered files, which could lead to a memory leak...
CVE-2025-39793
In the Linux kernel, the following vulnerability has been resolved: iouring/memmap: cast nrpages to sizet before shifting If the allocated size exceeds UINTMAX, then it's necessary to cast the mr-nrpages value to sizet to prevent it from overflowing. In practice this isn't much of a concern as th...

In practice this isn't much of a concern as th...
CVE-2025-39793
Summary (CVE-2025-39793): In the Linux kernel io_uring/memmap path, the vulnerability arises when allocating memory where nr_pages may overflow during a shift if the size exceeds UINT_MAX. The root cause is failure to cast mr->nr_pages to size_t before shifting, which could allow overflow and ...
