Details

In the Linux kernel, the following vulnerability has been resolved: ubi: Fix UAF wear-leveling entry in eraseblkcountseqshow() Wear-leveling entry could be freed in error path, which may be accessed again in eraseblkcountseqshow(), for example: _eraseworker eraseblkcountseqshow wl = ubi->lookuptbl[*blocknumber] if (wl) wlentrydestroy ubi->lookuptbl[e->pnum] = NULL kmemcachefree(ubiwlentryslab, e) erasecount = wl->ec // UAF! Wear-leveling entry updating/accessing in ubi->lookuptbl should be protected by ubi->wllock, fix it by adding ubi->wllock to serialize wl entry accessing between wlentrydestroy() and eraseblkcountseq_show(). Fetch a reproducer in [Link].
