In the Linux kernel, the following vulnerability has been resolved: net: ipv6: fix NOREF dst use in seg6 and rpl lwtunnels seg6inputcore and rplinput call ip6routeinput which sets a NOREF dst on the skb, then pass it to dstcachesetip6 invoking dsthold unconditionally. On PREEMPTRT, ksoftirqd is...

CVE-2026-46099

The CVE-2026-46099 entry describes a use-after-free race in Linux kernel IPv6 handling for seg6 and rpl lightweight tunnels. A NOREF destination cached during ip6_route_input() can be freed by a concurrent FIB lookup on a shared nexthop under PREEMPT_RT, leading to a WARN or potential instability...

CVE-2026-46049

CVE-2026-46049 concerns the Linux kernel ALSA ctxfi driver (S/PDIF path). The issue arises in spdif_passthru_playback_setup() when pll_rate is not updated (remains 0), causing the MSR calculation loop to spin if 32000 Hz is skipped. The fix adds a fallback: if atc->pll_rate is 0, use atc->r...

CVE-2026-46048

CVE-2026-46048 relates to a leak in the Linux kernel ALSA caiaq driver. The issue arises because create_card() takes a usb_get_dev() reference to a USB device and stores the corresponding usb_put_dev() in card_free(), which is registered as snd_card’s private_free destructor. However, private_fre...

CVE-2026-45996

The CVE-2026-45996 entry concerns a use-after-free in the Linux kernel SPI IMX driver (on unbind/deregistration). The root cause is that upon deregistering the SPI controller, driver data may be freed while still referenced, requiring an extra reference before deregistration to ensure data remain...
