CVE-2026-23207

CVE-2026-23207 concerns the Linux kernel SPI Tegra210 quad driver. The issue arose because curr_xfer accesses were not consistently protected by the lock in the IRQ thread path, enabling a race against the timeout path where curr_xfer could be NULL after being cleared but still dereferenced in ha...

CVE-2026-31508

The CVE-2026-31508 issue affects the Linux kernel in the Open vSwitch teardown path. The root cause is that after a patch, the teardown code for OVS ports no longer unconditionally takes the RTNL, allowing netdev_destroy() to finish and free the netdev before unregistration completes if the IFF_O...

CVE-2026-45914

CVE-2026-45914 affects the Linux kernel hwmon ibmpex driver, where a race during sensor deletion can race with userspace access to a freed sensor data structure, causing a use-after-free and potential crash. The description notes that the patch reverting the previous fix (6946c726…) may introduce...

CVE-2026-23202

The CVE-2026-23202 issue is in the Linux kernel SPI driver for Tegra210-quad (tegra_qspi_combined_seq_xfer). The root cause is that curr_xfer is read by the IRQ handler without the spinlock, and is cleared without proper synchronization, allowing a race that could yield a NULL pointer dereference...

CVE-2026-22988

CVE-2026-22988 affects the Linux kernel’s arp handling, specifically the assumption that skb->head remains unchanged after dev_hard_header() in arp_create(). The issue arises when a recent commit altered skb->head, breaking that assumption. The publicly provided description and OpenVAS/Ness...

CVE-2026-53182

CVE-2026-53182 affects the Linux kernel nl80211: rejects oversized EMA RNR lists in nl80211_parse_rnr_elems, using a u8 counter and capping at 255 to align with the underlying data structure. Several advisories (Red Hat, Debian family, Ubuntu OSV entries, and Root) confirm patches are released in...
