In the Linux kernel, the following vulnerability has been resolved:
fuse: fix io-uring list corruption for terminated non-committed requests
When a request is terminated before it has been committed, the request
is not removed from the queue's list. This leaves a dangling list entry
that leads to list corruption and use-after-free issues.
Remove the request from the queue's list for terminated non-committed
requests.

Title: Linux kernel vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
Josh Eads, Kristoffer Janke, Eduardo Vela Nava, Tavis Ormandy, and Matteo
Rizzo discovered that some AMD Zen processors did not properly verify the
signature of CPU microcode. This flaw is known as EntrySign. A privileged
attacker could possibly use this issue to cause load malicious CPU
microcode causing loss of integrity and confidentiality. (CVE-2024-36347)
Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
