CVE-2026-63984

CVE-2026-63984 affects the Linux kernel, addressing an overflow in the IPv6 RPL SRH decompression path. The bug occurs in ipv6_rpl_srh_decompress(): hdrlen is computed as outhdr->hdrlen = (((n + 1) * sizeof(struct in6_addr)) >> 3); since hdrlen is an 8-bit value, for n >= 127 the resu...

CVE-2026-63963

Summary: CVE-2026-63963 affects the Linux kernel USB Type-C TCPM code. Specifically, in Discover Identity ACK handlers, the VDO count passed from a device must be validated before calling svdm_consume_identity() or svdm_consume_identity_sop_prime(). The device-controlled value could index off the...

CVE-2026-63961

In the Linux kernel, the following vulnerability has been resolved: usb: typec: altmodes/displayport: validate count before reading Status Update VDO A broken/malicious device can send the incorrect count for a status update VDO, which will cause the kernel to read uninitialized stack data and se...

CVE-2026-63954

CVE-2026-63954 pertains to the Linux kernel, specifically the hpfs driver. The issue occurs when hpfs_map_dnode_bitmap fails, which would cause the code to call hpfs_brelse4 on an uninitialized quad buffer head, resulting in a crash. The vulnerability has been resolved by the kernel patch referen...

CVE-2026-63952

CVE-2026-63952 affects the Linux kernel: when SEAL_EXEC is added, SEAL_WRITE is implied to enforce W^X, but the implied seal is applied after the write-mapping check. This allows a memfd to be modified via writable mappings despite being marked as write-sealed. The fix adds the implied seals befo...

CVE-2026-63912

The CVE concerns the Linux kernel XFRM/ESP path. The vulnerability arises in the ESP out-of-place fast path where an out-of-line trailer is written before dest page frag allocation; the head gate and tail code previously treated skb->data_len and tailen separately, risking an overflow when the...

CVE-2026-63905

CVE-2026-63905 concerns the Linux kernel’s usbip vudc path, resolving a use-after-free in vudc_remove caused by a race with a timer. The issue arises because vudc_probe() binds an embedded timer to vudc->tr_timer.timer, and usbip_sockfd_store() can start the timer, while vudc_remove() may free...
