CVSS: 6.0EPSS: 0%CPEs: 3EXPL: 0CVE-2024-45020 – bpf: Fix a kernel verifier crash in stacksafe()
https://notcve.org/view.php?id=CVE-2024-45020
In the Linux kernel, the following vulnerability has been resolved: bpf: Fix a kernel verifier crash in stacksafe() Daniel Hodges reported a kernel verifier crash when playing with sched-ext. Further investigation shows that the crash is due to invalid memory access in stacksafe(). More specifically, it is the following code: if (exact != NOT_EXACT && old->stack[spi].slot_type[i % BPF_REG_SIZE] != cur->stack[spi].slot_type[i % BPF_REG_SIZE]) return false; The 'i' iterates old->allocated_stack. If cur->allocated_stack < old->allocated_stack the out-of-bound access will happen. To fix the issue add 'i >= cur->allocated_stack' check such that if the condition is true, stacksafe() should fail. Otherwise, cur->stack[spi].slot_type[i % BPF_REG_SIZE] memory access is legal. • https://git.kernel.org/stable/c/ab470fefce2837e66b771c60858118d50bb5bb10 https://git.kernel.org/stable/c/2793a8b015f7f1caadb9bce9c63dc659f7522676 https://git.kernel.org/stable/c/7cad3174cc79519bf5f6c4441780264416822c08 https://git.kernel.org/stable/c/6e3987ac310c74bb4dd6a2fa8e46702fe505fb2b https://git.kernel.org/stable/c/bed2eb964c70b780fb55925892a74f26cb590b25 https://access.redhat.com/security/cve/CVE-2024-45020 https://bugzilla.redhat.com/show_bug.cgi?id=2311717 • CWE-125: Out-of-bounds Read •

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Take state lock during tx timeout reporter mlx5e_safe_reopen_channels() requires the state lock taken. The referenced changed in the Fixes tag removed the lock to fix another issue. This patch adds it back but at a later point (when calling mlx5e_safe_reopen_channels()) to avoid the deadlock referenced in the Fixes tag. • https://git.kernel.org/stable/c/514232495aa523641febaa58b687fe6df1cd0b73 https://git.kernel.org/stable/c/8ce3d969348a7c7fa3469588eb1319f9f3cc0eaa https://git.kernel.org/stable/c/eab0da38912ebdad922ed0388209f7eb0a5163cd https://git.kernel.org/stable/c/03d3734bd692affe4d0e9c9d638f491aaf37411b https://git.kernel.org/stable/c/b3b9a87adee97854bcd71057901d46943076267e https://git.kernel.org/stable/c/8e57e66ecbdd2fddc9fbf3e984b1c523b70e9809 https://git.kernel.org/stable/c/e6b5afd30b99b43682a7764e1a74a42fe4d5f4b3 •
