https://notcve.org/view.php?id=CVE-2024-41079
In the Linux kernel, the following vulnerability has been resolved: nvmet: always initialize cqe.result The spec doesn't mandate that the first two double words (aka results) for the command queue entry need to be set to 0 when they are not used (not specified). Though, the target implemention returns 0 for TCP and FC but not for RDMA. Let's make RDMA behave the same and thus explicitly initializing the result field. This prevents leaking any data from the stack. • https://git.kernel.org/stable/c/30d35b24b7957922f81cfdaa66f2e1b1e9b9aed2 https://git.kernel.org/stable/c/10967873b80742261527a071954be8b54f0f8e4d https://git.kernel.org/stable/c/0990e8a863645496b9e3f91cfcfd63cd95c80319 https://git.kernel.org/stable/c/cd0c1b8e045a8d2785342b385cb2684d9b48e426 https://access.redhat.com/security/cve/CVE-2024-41079 https://bugzilla.redhat.com/show_bug.cgi?id=2300456 • CWE-402: Transmission of Private Resources into a New Sphere ('Resource Leak') •

https://notcve.org/view.php?id=CVE-2024-41078
In the Linux kernel, the following vulnerability has been resolved: btrfs: qgroup: fix quota root leak after quota disable failure If during the quota disable we fail when cleaning the quota tree or when deleting the root from the root tree, we jump to the 'out' label without ever dropping the reference on the quota root, resulting in a leak of the root since fs_info->quota_root is no longer pointing to the root (we have set it to NULL just before those steps). Fix this by always doing a btrfs_put_root() call under the 'out' label. This is a problem that exists since qgroups were first added in 2012 by commit bed92eae26cc ("Btrfs: qgroup implementation and prototypes"), but back then we missed a kfree on the quota root and free_extent_buffer() calls on its root and commit root nodes, since back then roots were not yet reference counted. • https://git.kernel.org/stable/c/94818bdb00ef34a996a06aa63d11f591074cb757 https://git.kernel.org/stable/c/8a69529f22590b67bb018de9acbcf94abc8603cf https://git.kernel.org/stable/c/5ef3961682e5310f2221bae99bcf9f5d0f4b0d51 https://git.kernel.org/stable/c/f88aeff5a173e8ba3133314eb4b964236ef3589d https://git.kernel.org/stable/c/7dd6a5b96157a21245566b21fd58276a214357ff https://git.kernel.org/stable/c/a7e4c6a3031c74078dba7fa36239d0f4fe476c53 •

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 •

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 •
