vsock/virtio: Initialization of the dangling pointer occurring in vsk->trans

2024-11-14T12:19:41+00:00

commit 6ca575374dd9a507cdd16dfa0e78c2e9e20bd05f upstream. During loopback communication, a dangling pointer can be created in vsk->trans, potentially leading to a Use-After-Free condition. This issue is resolved by initializing vsk->trans to NULL.

hv_sock: Initializing vsk->trans to NULL to prevent a dangling pointer

2024-11-14T12:19:41+00:00

commit e629295bd60abf4da1db85b82819ca6a4f6c1e79 upstream. When hvs is released, there is a possibility that vsk->trans may not be initialized to NULL, which could lead to a dangling pointer.

ASoC: amd: yc: fix internal mic on Xiaomi Book Pro 14 2022

2024-11-14T12:19:40+00:00

commit de156f3cf70e17dc6ff4c3c364bb97a6db961ffd upstream. Xiaomi Book Pro 14 2022 (MIA2210-AD) requires a quirk entry for its internal microphone to be enabled. This is likely due to similar reasons as seen previously on Redmi Book 14/15 Pro 2022 models (since they likely came with similar firmware): - commit dcff8b7ca92d ("ASoC: amd: yc: Add Xiaomi Redmi Book Pro 15 2022 into DMI table") - commit c1dd6bf61997 ("ASoC: amd: yc: Add Xiaomi Redmi Book Pro 14 2022 into DMI table") A quirk would likely be needed for Xiaomi Book Pro 15 2022 models, too. However, I do not have such device on hand so I will leave it for now.

ucounts: fix counter leak in inc_rlimit_get_ucounts()

commit 432dc0654c612457285a5dcf9bb13968ac6f0804 upstream. The inc_rlimit_get_ucounts() increments the specified rlimit counter and then checks its limit. If the value exceeds the limit, the function returns an error without decrementing the counter.

But the following 'rc' check is wrong and execution flow do 'ocfs2_xa_remove_entry(loc);' twice: * 1st: in ocfs2_xa_cleanup_value_truncate(); * 2nd: returning back to ocfs2_xa_remove() instead of going to 'out'.

irqchip/gic-v3: Force propagation of the active state with a read-back

2024-11-14T12:19:40+00:00

commit 464cb98f1c07298c4c10e714ae0c36338d18d316 upstream. Christoffer reports that on some implementations, writing to GICR_ISACTIVER0 (and similar GICD registers) can race badly with a guest issuing a deactivation of that interrupt via the system register interface. There are multiple reasons to this: - this uses an early write-acknoledgement memory type (nGnRE), meaning that the write may only have made it as far as some interconnect by the time the store is considered "done" - the GIC itself is allowed to buffer the write until it decides to take it into account (as long as it is in finite time) The effects are that the activation may not have taken effect by the time the kernel enters the guest, forcing an immediate exit, or that a guest deactivation occurs before the interrupt is active, doing nothing. In order to guarantee that the write to the ISACTIVER register has taken effect, read back from it, forcing the interconnect to propagate the write, and the GIC to process the write before returning the read.
