In the Linux kernel, the following vulnerability has been resolved: null_blk: fix validation of block size Block size should be between 512 and PAGE_SIZE and be a power of 2. The current check does not validate this, so update the check. Without this patch, null_blk would Oops due to a null pointer deref when loaded with bs=1536 [1].

In the Linux kernel, the following vulnerability has been resolved: NFSv4: Fix memory leak in nfs4_set_security_label We leak nfs_fattr and nfs4_label every time we set a security xattr. A vulnerability was found in the nfs4_set_security_label() in the Linux kernel, where the function fails to free the nfs_fattr attribute before exiting, leaving said memory allocation present. As the nfs4_set_security_label() is called repeatedly over time, this may lead to memory exhaustion. • https://git.kernel.org/stable/c/899604a7c958771840941caff9ee3dd8193d984c https://git.kernel.org/stable/c/b98090699319e64f5de1e8db5bb75870f1eb1c6e https://git.kernel.org/stable/c/d130220ccc94d74d70da984a199477937e7bf03c https://git.kernel.org/stable/c/aad11473f8f4be3df86461081ce35ec5b145ba68 https://access.redhat.com/security/cve/CVE-2024-41076 https://bugzilla.redhat.com/show_bug.cgi?id=2300453 • CWE-401: Missing Release of Memory after Effective Lifetime •

https://notcve.org/view.php?id=CVE-2024-41075
In the Linux kernel, the following vulnerability has been resolved: cachefiles: add consistency check for copen/cread This prevents malicious processes from completing random copen/cread requests and crashing the system. Added checks are listed below: * Generic, copen can only complete open requests, and cread can only complete read requests. * For copen, ondemand_id must not be 0, because this indicates that the request has not been read by the daemon. * For cread, the object corresponding to fd and req should be the same. • https://git.kernel.org/stable/c/3b744884c0431b5a62c92900e64bfd0ed61e8e2a https://git.kernel.org/stable/c/36d845ccd7bf527110a65fe953886a176c209539 https://git.kernel.org/stable/c/8aaa6c5dd2940ab934d6cd296175f43dbb32b34a https://git.kernel.org/stable/c/a26dc49df37e996876f50a0210039b2d211fdd6f •

https://notcve.org/view.php?id=CVE-2024-41074
In the Linux kernel, the following vulnerability has been resolved: cachefiles: Set object to close if ondemand_id < 0 in copen If copen is maliciously called in the user mode, it may delete the request corresponding to the random id. And the request may have not been read yet. Note that when the object is set to reopen, the open request will be done with the still reopen state in above case. As a result, the request corresponding to this object is always skipped in select_req function, so the read request is never completed and blocks other process. Fix this issue by simply set object to close if its id < 0 in copen. • https://git.kernel.org/stable/c/703bea37d13e4ccdafd17ae7c4cb583752ba7663 https://git.kernel.org/stable/c/c32ee78fbc670e6f90989a45d340748e34cad333 https://git.kernel.org/stable/c/0845c553db11c84ff53fccd59da11b6d6ece4a60 https://git.kernel.org/stable/c/4f8703fb3482f92edcfd31661857b16fec89c2c0 •
