CVSS: 5.5EPSS: 0%CPEs: 6EXPL: 0CVE-2024-42082 – xdp: Remove WARN() from __xdp_reg_mem_model()
https://notcve.org/view.php?id=CVE-2024-42082
In the Linux kernel, the following vulnerability has been resolved: xdp: Remove WARN() from __xdp_reg_mem_model() syzkaller reports a warning in __xdp_reg_mem_model(). The warning occurs only if __mem_id_init_hash_table() returns an error. It returns the error in two cases: 1. memory allocation fails; 2. rhashtable_init() fails when some fields of rhashtable_params struct are not initialized properly. The second case cannot happen since there is a static const rhashtable_params struct with valid fields. So, warning is only triggered when there is a problem with memory allocation. Thus, there is no sense in using WARN() to handle this error and it can be safely removed.

In the Linux kernel, the following vulnerability has been resolved: RDMA/restrack: Fix potential invalid address access struct rdma_restrack_entry's kern_name was set to KBUILD_MODNAME in ib_create_cq(), while if the module exited but forgot del this rdma_restrack_entry, it would cause a invalid address access in rdma_restrack_clean() when print the owner of this rdma_restrack_entry. These code is used to help find one forgotten PD release in one of the ULPs. But it is not needed anymore, so delete them. • https://git.kernel.org/stable/c/8656ef8a9288d6c932654f8d3856dc4ab1cfc6b5 https://git.kernel.org/stable/c/782bdaf9d01658281bc813f3f873e6258aa1fd8d https://git.kernel.org/stable/c/8ac281d42337f36cf7061cf1ea094181b84bc1a9 https://git.kernel.org/stable/c/f45b43d17240e9ca67ebf3cc82bb046b07cc1c61 https://git.kernel.org/stable/c/ca537a34775c103f7b14d7bbd976403f1d1525d8 •

In the Linux kernel, the following vulnerability has been resolved: gfs2: Fix NULL pointer dereference in gfs2_log_flush In gfs2_jindex_free(), set sdp->sd_jdesc to NULL under the log flush lock to provide exclusion against gfs2_log_flush(). In gfs2_log_flush(), check if sdp->sd_jdesc is non-NULL before dereferencing it. Otherwise, we could run into a NULL pointer dereference when outstanding glock work races with an unmount (glock_work_func -> run_queue -> do_xmote -> inode_go_sync -> gfs2_log_flush). • https://git.kernel.org/stable/c/3429ef5f50909cee9e498c50f0c499b9397116ce https://git.kernel.org/stable/c/f54f9d5368a4e92ede7dd078a62788dae3a7c6ef https://git.kernel.org/stable/c/35264909e9d1973ab9aaa2a1b07cda70f12bb828 https://access.redhat.com/security/cve/CVE-2024-42079 https://bugzilla.redhat.com/show_bug.cgi?id=2300517 • CWE-476: NULL Pointer Dereference •

https://notcve.org/view.php?id=CVE-2024-42078
In the Linux kernel, the following vulnerability has been resolved: nfsd: initialise nfsd_info.mutex early. nfsd_info.mutex can be dereferenced by svc_pool_stats_start() immediately after the new netns is created. Currently this can trigger an oops. Move the initialisation earlier before it can possibly be dereferenced. • https://git.kernel.org/stable/c/7b207ccd983350a5dedd132b57c666186dd02a7c https://git.kernel.org/stable/c/7e8b94045bc77ce4f085ddfb9eb04e5760e66169 https://git.kernel.org/stable/c/e0011bca603c101f2a3c007bdb77f7006fa78fb1 https://access.redhat.com/security/cve/CVE-2024-42078 https://bugzilla.redhat.com/show_bug.cgi?id=2300516 • CWE-457: Use of Uninitialized Variable •
