CVE-2026-53042 fwctl: Fix class init ordering to avoid NULL pointer dereference on device removal

In the Linux kernel, the following vulnerability has been resolved: fwctl: Fix class init ordering to avoid NULL pointer dereference on device removal CXL is linked before fwctl in drivers/Makefile. Both use moduleinit, so cxlpcidriverinit runs first. When cxlpciprobe calls fwctlregister and then...

CVE-2026-53016

Summary of CVE-2026-53016 (Linux kernel): The vulnerability exists in the crypto CCP driver when handling AF_ALG rfc3686-ctr-aes-ccp requests. The function ccp_aes_complete() restores AES_BLOCK_SIZE bytes into the caller’s IV buffer, but RFC3686 skciphers expose an 8-byte IV, leading to a buffer ...

CVE-2026-53009 ice: fix double-free of tx_buf skb

In the Linux kernel, the following vulnerability has been resolved: ice: fix double-free of txbuf skb If icetso or icetxcsum fail, the error path in icexmitframering frees the skb, but the 'first' txbuf still points to it and is marked as valid ICETXBUFSKB. 'nexttouse' remains unchanged, so the...

CVE-2026-52985

In the Linux kernel, the following vulnerability has been resolved: netdevsim: zero initialize struct iphdr in dummy skbuff Syzbot reports a KMSAN uninit-value originating from nsimdevtrapskbbuild, with the allocation also being performed in the same function. Fix this by calling skbputzero inste...

CVE-2026-52985

CVE-2026-52985 concerns the Linux kernel in the netdevsim feature, where the IP header in a dummy skb was not zero-initialized in nsim_dev_trap_skb_build. The issue arises from using skb_put instead of skb_put_zero, leading to uninitialized values in the IP header and potential memory/safety impl...
