CVE-2022-49190

CVE-2022-49190 affects the Linux kernel (kernel/resource). Root cause: boot memory allocated via alloc_resource() may be leaked if callers use kfree directly, causing a kernel BUG; remediation leaks only a few bytes to avoid patching every call site. A fix was applied in the kernel (commit ebff7d...

CVE-2022-49049 mm/secretmem: fix panic when growing a memfd_secret

In the Linux kernel, the following vulnerability has been resolved: mm/secretmem: fix panic when growing a memfdsecret When one tries to grow an existing memfdsecret with ftruncate, one gets a panic 1. For example, doing the following reliably induces the panic: fd = memfdsecret; ftruncatefd, 10;...

CVE-2022-49049

CVE-2022-49049 concerns the Linux kernel mm/secretmem path (memfd_secret) where growing a secret memfd via ftruncate could trigger a kernel panic when zeroing pages during truncation. The issue arises because memfd_secret pages are not mapped via the direct map, so page_address() results could be...
