CVE-2026-98844

The Linux kernel contains a vulnerability in the netfs component where the pagecache is not properly cleared when a file is extended via a write operation. Specifically, dirty data left by writes through an mmapped region in a hole created after the End-of-File (EOF) could persist. The fix involv...

CVE-2026-98842

The Linux kernel contains a vulnerability where the codetag_load_module() function fails to set the error code upon failure. Consequently, load_module() incorrectly returns 0 after the module has been torn down. Additionally, if the module is a livepatch , the mod->klp_info allocated by copy_m...

CVE-2026-98840 vc_screen: reload vc pointer before if (ret) in vcs_write() to avoid UAF

In the Linux kernel, the following vulnerability has been resolved: vcscreen: reload vc pointer before if ret in vcswrite to avoid UAF The reload of 'vc' added by commit 8fb9ea65c9d1 "vcscreen: reload load of struct vcdata pointer in vcswrite to avoid UAF" sits after the 'if ret' block, so the...

CVE-2026-98840

The Linux kernel is vulnerable to a Use-After-Free (UAF) condition within the vcs_write() function. The root cause is that the reload of the vc pointer occurs after an if (ret) block; consequently, a copy-failure break path can exit the loop without reloading the pointer. If the vc structure is f...
