DEBIAN-CVE-2026-68144

In the Linux kernel, the following vulnerability has been resolved:  phonet: pep: fix use-after-free in pepgetsb()  pepgetsb() doesn't consider that pskbmaypull() might have relocated the skb data, and continue to access the older pointer, causing UAF.  Reproduced under KASAN:    BUG: KASAN: slab-use-after-free in pepgetsb+0x234/0x3b0   Read of size 1 at addr ff11000105510f50 by task repro/157    pepgetsb+0x234/0x3b0    pipehandlerdorcv+0x5f7/0xa10    pepdorcv+0x203/0x410    skreceiveskb+0x471/0x4a0    phonetrcv+0x5b3/0x6c0    _netifreceiveskb+0xcc/0x1d0  Refetch the header with skbheaderpointer() after pskbmay_pull(), so the possibly stale pointer is no longer dereferenced. There are better ways to solve this, but, this is the less instrusive one.
