CVSS: 5.7EPSS: 0%CPEs: 8EXPL: 0CVE-2024-42084 – ftruncate: pass a signed offset
https://notcve.org/view.php?id=CVE-2024-42084
In the Linux kernel, the following vulnerability has been resolved: ftruncate: pass a signed offset The old ftruncate() syscall, using the 32-bit off_t misses a sign extension when called in compat mode on 64-bit architectures. As a result, passing a negative length accidentally succeeds in truncating to file size between 2GiB and 4GiB. Changing the type of the compat syscall to the signed compat_off_t changes the behavior so it instead returns -EINVAL. The native entry point, the truncate() syscall and the corresponding loff_t based variants are all correct already and do not suffer from this mistake. An unexpected file truncate flaw was found when opening files with specific parameters in the Linux kernel's file-system. This vulnerability allows a local user to corrupt specific files when having access to these files. • https://git.kernel.org/stable/c/3f6d078d4accfff8b114f968259a060bfdc7c682 https://git.kernel.org/stable/c/c329760749b5419769e57cb2be80955d2805f9c9 https://git.kernel.org/stable/c/f531d4bc6c5588d713359e42ed65e46816d841d8 https://git.kernel.org/stable/c/84bf6b64a1a0dfc6de7e1b1c776d58d608e7865a https://git.kernel.org/stable/c/dbb226d81cd02cee140139c2369791e6f61f2007 https://git.kernel.org/stable/c/5ae6af68410bdad6181ec82104bb9985a7a6a0fa https://git.kernel.org/stable/c/836359247b0403e0634bfbc83e5bb8063fad287a https://git.kernel.org/stable/c/930a4c369f74da26816eaaa71b5888d29 • CWE-96: Improper Neutralization of Directives in Statically Saved Code ('Static Code Injection') •
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 gfs2_log_flush(), check if sdp->sd_jdesc is non-NULL before dereferencing it.
