This allows an invalid size to propagate in...

CVE-2022-50543

In CVE-2022-50543, Linux kernel RDMA/rxe has a double free of mr->map when rxe_mr_init_user() fails and rxe_mr_cleanup() is called. The root cause involved freeing mr->map twice in the error path, traced through prior commits and a revert, and has been fixed by making rxe_mr_cleanup() free ...

CVE-2023-53151

CVE-2023-53151 affects the Linux kernel’s md/raid10 path. The vulnerability arose because there was no limit for plugged bio during flush writes in raid10 (unlike raid1 which used cond_resched), allowing writeback activity to cause a soft lockup under heavy I/O. The public advisories describe a f...

CVE-2023-53191

The CVE-2023-53191 vulnerability affects the Linux kernel code path irqchip/alpine-msi in alpine_msix_init_domains.

CVE-2023-53432

CVE-2023-53432 : Linux kernel vulnerability in the FireWire net path (firewire: net: fix use after free in fwnet_finish_incoming_packet()). The netif_rx() path frees the skb, so dereferencing skb->len could use freed memory. The incident is reported as resolved in the provided description; no ...

CVE-2023-53555

CVE-2023-53555 relates to the Linux kernel (Damon/DAMON subsystem). The issue: in damos_new_filter(), the newly allocated filter object’s list field was not initialized, and the sysfs DAMON interface and DAMON_RECLAIM path did not reinitialize it after calling damos_new_filter(). This allowed acc...

CVE-2025-38121

The CVE-2025-38121 entry describes a Linux kernel issue in the wifi: iwlwifi: mld path. When an error occurs during init, in_hw_restart is set but never cleared, causing the code to retry init as if in a restart while not actually in one. This can lead to a NULL pointer dereference during cancell...

CVE-2025-38224

CVE-2025-38224 concerns the Linux kernel’s can: kvaser_pciefd driver where echo_skb_max was defined as 17 (KVASER_PCIEFD_CAN_TX_MAX_COUNT) but later rounded to the next power of two (32).
