[PATCH openEuler-1.0-LTS] net/sched: act_skbmod: prevent kernel-infoleak

From: Eric Dumazet <edumazet(a)google.com> stable inclusion from stable-v4.19.312 commit f190a4aa03cbd518bd9c62a66e1233984f5fd2ec category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9QG2F CVE: CVE-2024-35893 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit d313eb8b77557a6d5855f42d2234bd592c7b50dd upstream. syzbot found that tcf_skbmod_dump() was copying four bytes from kernel stack to user space [1]. The issue here is that 'struct tc_skbmod' has a four bytes hole. We need to clear the structure before filling fields.

[PATCH openEuler-22.03-LTS-SP1] Fix page corruption caused by racy check in __free_pages
by Ze Zuo 06 Jun '24

06 Jun '24

From: David Chen <david.chen(a)nutanix.com> stable inclusion from stable-v5.10.168 commit 0a626e27f984dfbe96bd8e4fd08f20a2ede3ea23 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9R4KT CVE: CVE-2023-52739 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 462a8e08e0e6287e5ce13187257edbf24213ed03 upstream. When we upgraded our kernel, we started seeing some page corruption like the following consistently: BUG: Bad page state in process ganesha.nfsd pfn:1304ca page:0000000022261c55 refcount:0 mapcount:-128 mapping:0000000000000000 index:0x0 pfn:0x1304ca flags: 0x17ffffc0000000() raw: 0017ffffc0000000 ffff8a513ffd4c98 ffffeee24b35ec08 0000000000000000 raw: 0000000000000000 0000000000000001 00000000ffffff7f 0000000000000000 page dumped because: nonzero mapcount CPU: 0 PID: 15567 Comm: ganesha.nfsd Kdump: loaded Tainted: P B O 5.10.158-1.nutanix.20221209.el7.x86_64 #1 Hardware name: VMware, Inc. VMware Virtual Platform/440BX Desktop Reference Platform, BIOS 6.00 04/05/2016 Call Trace: dump_stack+0x74/0x96 bad_page.cold+0x63/0x94 check_new_page_bad+0x6d/0x80 rmqueue+0x46e/0x970 get_page_from_freelist+0xcb/0x3f0 ? _cond_resched+0x19/0x40 __alloc_pages_nodemask+0x164/0x300 alloc_pages_current+0x87/0xf0 skb_page_frag_refill+0x84/0x110 ... Sometimes, it would also show up as corruption in the free list pointer and cause crashes. After bisecting the issue, we found the issue started from commit e320d3012d25 ("mm/page_alloc.c: fix freeing non-compound pages"): if (put_page_testzero(page)) free_the_page(page, order); else if (!PageHead(page)) while (order-- > 0) free_the_page(page + (1 << order), order); So the problem is the check PageHead is racy because at this point we already dropped our reference to the page. So even if we came in with compound page, the page can already be freed and PageHead can return false and we will end up freeing all the tail pages causing double free.

[PATCH openEuler-1.0-LTS] media: imon: fix access to invalid resource for the second interface
by dinglongwei 05 Jun '24

05 Jun '24

From: Takashi Iwai <tiwai(a)suse.de> stable inclusion from stable-v5.10.202 commit 0f5068519f89d928d6c51100e4b274479123829f category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9R4N0 CVE: CVE-2023-52754 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit a1766a4fd83befa0b34d932d532e7ebb7fab1fa7 ] imon driver probes two USB interfaces, and at the probe of the second interface, the driver assumes blindly that the first interface got bound with the same imon driver. It's usually true, but it's still possible that the first interface is bound with another driver via a malformed descriptor. Then it may lead to a memory corruption, as spotted by syzkaller; imon driver accesses the data from drvdata as struct imon_context object although it's a completely different one that was assigned by another driver. This patch adds a sanity check -- whether the first interface is really bound with the imon driver or not -- for avoiding the problem above at the probe time.
