[PATCH OLK-5.10] media: v4l2-tpg: prevent the risk of a division by zero
by Zhao Yipeng 26 Dec '24

From: Mauro Carvalho Chehab <mchehab+huawei(a)kernel.org> stable inclusion from stable-v5.10.230 commit 054931ca3cfcb8e8fa036e887d6f379942b02565 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB5ATB CVE: CVE-2024-50287 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=… -------------------------------- media: v4l2-tpg: prevent the risk of a division by zero commit e6a3ea83fbe15d4818d01804e904cbb0e64e543b upstream. As reported by Coverity, the logic at tpg_precalculate_line() blindly rescales the buffer even when scaled_witdh is equal to zero. If this ever happens, this will cause a division by zero. Instead, add a WARN_ON_ONCE() to trigger such cases and return without doing any precalculation.

[PATCH OLK-5.10] x86/sgx: Fix deadlock in SGX NUMA node search
by Zhao Yipeng 26 Dec '24

26 Dec '24

From: Aaron Lu <aaron.lu(a)intel.com> mainline inclusion from mainline-v6.12-rc1 commit 9c936844010466535bd46ea4ce4656ef17653644 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAYQRL CVE: CVE-2024-49856 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- x86/sgx: Fix deadlock in SGX NUMA node search When the current node doesn't have an EPC section configured by firmware and all other EPC sections are used up, CPU can get stuck inside the while loop that looks for an available EPC page from remote nodes indefinitely, leading to a soft lockup. Note how nid_of_current will never be equal to nid in that while loop because nid_of_current is not set in sgx_numa_mask. Also worth mentioning is that it's perfectly fine for the firmware not to setup an EPC section on a node. While setting up an EPC section on each node can enhance performance, it is not a requirement for functionality. Rework the loop to start and end on *a* node that has SGX memory. This avoids the deadlock looking for the current SGX-lacking node to show up in the loop when it never will.
