In the Linux kernel, the following vulnerability has been resolved: drm/i915/gem: Really move i915_gem_context.link under ref protection i915_perf assumes that it can use the i915_gem_context reference to protect its i915->gem.contexts.list iteration. However, this requires that we do not remove the context from the list until after we drop the final reference and release the struct. If, as currently, we remove the context from the list during context_close(), the link.next pointer may be poisoned while we are holding the context reference and cause a GPF: [ 4070.573157] i915 0000:00:02.0: [drm:i915_perf_open_ioctl [i915]] filtering on ctx_id=0x1fffff ctx_id_mask=0x1fffff [ 4070.574881] general protection fault, probably for non-canonical address 0xdead000000000100: 0000 [#1] PREEMPT SMP [ 4070.574897] CPU: 1 PID: 284392 Comm: amd_performance Tainted: G E 5.17.9 #180 [ 4070.574903] Hardware name: Intel Corporation NUC7i5BNK/NUC7i5BNB, BIOS BNKBL357.86A.0052.2017.0918.1346 09/18/2017 [ 4070.574907] RIP: 0010:oa_configure_all_contexts.isra.0+0x222/0x350 [i915] [ 4070.574982] Code: 08 e8 32 6e 10 e1 4d 8b 6d 50 b8 ff ff ff ff 49 83 ed 50 f0 41 0f c1 04 24 83 f8 01 0f 84 e3 00 00 00 85 c0 0f 8e fa 00 00 00 <49> 8b 45 50 48 8d 70 b0 49 8d 45 50 48 39 44 24 10 0f 85 34 fe ff [ 4070.574990] RSP: 0018:ffffc90002077b78 EFLAGS: 00010202 [ 4070.574995] RAX: 0000000000000002 RBX: 0000000000000002 RCX: 0000000000000000 [ 4070.575000] RDX: 0000000000000001 RSI: ffffc90002077b20 RDI: ffff88810ddc7c68 [ 4070.575004] RBP: 0000000000000001 R08: ffff888103242648 R09: fffffffffffffffc [ 4070.575008] R10: ffffffff82c50bc0 R11: 0000000000025c80 R12: ffff888101bf1860 [ 4070.575012] R13: dead0000000000b0 R14: ffffc90002077c04 R15: ffff88810be5cabc [ 4070.575016] FS: 00007f1ed50c0780(0000) GS:ffff88885ec80000(0000) knlGS:0000000000000000 [ 4070.575021] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 4070.575025] CR2: 00007f1ed5590280 CR3: 000000010ef6f005 CR4: 00000000003706e0 [ 4070.575029] Call Trace: [ 4070.575033] <TASK> [ 4070.575037] lrc_configure_all_contexts+0x13e/0x150 [i915] [ 4070.575103] gen8_enable_metric_set+0x4d/0x90 [i915] [ 4070.575164] i915_perf_open_ioctl+0xbc0/0x1500 [i915] [ 4070.575224] ? asm_common_interrupt+0x1e/0x40 [ 4070.575232] ? i915_oa_init_reg_state+0x110/0x110 [i915] [ 4070.575290] drm_ioctl_kernel+0x85/0x110 [ 4070.575296] ? update_load_avg+0x5f/0x5e0 [ 4070.575302] drm_ioctl+0x1d3/0x370 [ 4070.575307] ? i915_oa_init_reg_state+0x110/0x110 [i915] [ 4070.575382] ? gen8_gt_irq_handler+0x46/0x130 [i915] [ 4070.575445] __x64_sys_ioctl+0x3c4/0x8d0 [ 4070.575451] ? __do_softirq+0xaa/0x1d2 [ 4070.575456] do_syscall_64+0x35/0x80 [ 4070.575461] entry_SYSCALL_64_after_hwframe+0x44/0xae [ 4070.575467] RIP: 0033:0x7f1ed5c10397 [ 4070.575471] Code: 3c 1c e8 1c ff ff ff 85 c0 79 87 49 c7 c4 ff ff ff ff 5b 5d 4c 89 e0 41 5c c3 66 0f 1f 84 00 00 00 00 00 b8 10 00 00 00 0f 05 <48> 3d 01 f0 ff ff 73 01 c3 48 8b 0d a9 da 0d 00 f7 d8 64 89 01 48 [ 4070.575478] RSP: 002b:00007ffd65c8d7a8 EFLAGS: 00000246 ORIG_RAX: 0000000000000010 [ 4070.575484] RAX: ffffffffffffffda RBX: 0000000000000006 RCX: 00007f1ed5c10397 [ 4070.575488] RDX: 00007ffd65c8d7c0 RSI: 0000000040106476 RDI: 0000000000000006 [ 4070.575492] RBP: 00005620972f9c60 R08: 000000000000000a R09: 0000000000000005 [ 4070.575496] R10: 000000000000000d R11: 0000000000000246 R12: 000000000000000a [ 4070.575500] R13: 000000000000000d R14: 0000000000000000 R15: 00007ffd65c8d7c0 [ 4070.575505] </TASK> [ 4070.575507] Modules linked in: nls_ascii(E) nls_cp437(E) vfat(E) fat(E) i915(E) x86_pkg_temp_thermal(E) intel_powerclamp(E) crct10dif_pclmul(E) crc32_pclmul(E) crc32c_intel(E) aesni_intel(E) crypto_simd(E) intel_gtt(E) cryptd(E) ttm(E) rapl(E) intel_cstate(E) drm_kms_helper(E) cfbfillrect(E) syscopyarea(E) cfbimgblt(E) intel_uncore(E) sysfillrect(E) mei_me(E) sysimgblt(E) i2c_i801(E) fb_sys_fops(E) mei(E) intel_pch_thermal(E) i2c_smbus ---truncated---

The version of kernel installed on the remote host is prior to 5.15.73-48.135. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.15-2022-009 advisory.

    2024-06-06: CVE-2022-48651 was added to this advisory.

    2024-06-06: CVE-2022-48658 was added to this advisory.

    2024-06-06: CVE-2022-48662 was added to this advisory.

    A flaw was found in the Linux kernel. The existing KVM SEV API has a vulnerability that allows a non-root     (host) user-level application to crash the host kernel by creating a confidential guest VM instance in AMD     CPU that supports Secure Encrypted Virtualization (SEV). (CVE-2022-0171)

    A flaw was found in the Linux kernel in vDPA with VDUSE backend. There were no checks in VDUSE kernel     driver to ensure the size of the device config space was in line with the features advertised by the VDUSE     userspace application. In case of a mismatch, Virtio drivers config read helpers did not initialize the     memory indirectly passed to vduse_vdpa_get_config() returning uninitialized memory from the stack. Such     memory was not directly propagated to userspace, although under some circumstances it could be printed in     the kernel logs. (CVE-2022-2308)

    A use-after-free flaw was found in the Linux kernel's Unix socket Garbage Collection and io_uring. This     flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-2602)

    A flaw use after free in the Linux kernel NILFS file system was found in the way user triggers function     security_inode_alloc to fail with following call to function nilfs_mdt_destroy. A local user could use     this flaw to crash the system or potentially escalate their privileges on the system. (CVE-2022-2978)

    Found Linux Kernel flaw in the i740 driver. The Userspace program could pass any values to the driver     through ioctl() interface. The driver doesn't check the value of 'pixclock', so it may cause a divide by     zero error. (CVE-2022-3061)

    An issue was discovered in the Linux kernel before 5.19. In pxa3xx_gcu_write in     drivers/video/fbdev/pxa3xx-gcu.c, the count parameter has a type conflict of size_t versus int, causing an     integer overflow and bypassing the size check. After that, because it is used as the third argument to     copy_from_user(), a heap overflow may occur. (CVE-2022-39842)

    This vulnerability allows local attackers to disclose sensitive information on affected installations of     the Linux Kernel 6.0-rc2. An attacker must first obtain the ability to execute high-privileged code on the     target system in order to exploit this vulnerability. The specific flaw exists within the nft_osf_eval     function. The issue results from the lack of proper initialization of memory prior to accessing it. An     attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the     context of the kernel. Was ZDI-CAN-18540. (CVE-2022-42432)

    drivers/usb/mon/mon_bin.c in usbmon in the Linux kernel before 5.19.15 and 6.x before 6.0.1 allows a user-     space client to corrupt the monitor's internal memory. (CVE-2022-43750)

    In the Linux kernel, the following vulnerability has been resolved: ipvlan: Fix out-of-bound bugs caused     by unset skb->mac_header If an AF_PACKET socket is used to send packets through ipvlan and the default     xmit function of the AF_PACKET socket is changed from dev_queue_xmit() to packet_direct_xmit() via     setsockopt() with the option name of PACKET_QDISC_BYPASS, the skb->mac_header may not be reset and remains     as the initial value of 65535, this may trigger slab-out-of-bounds bugs as following: (CVE-2022-48651)

    In the Linux kernel, the following vulnerability has been resolved: mm: slub: fix     flush_cpu_slab()/__free_slab() invocations in task context. Commit 5a836bf6b09f (mm: slub: move     flush_cpu_slab() invocations __free_slab() invocations out of IRQ context) moved all flush_cpu_slab()     invocations to the global workqueue to avoid a problem related with deactivate_slab()/__free_slab() being     called from an IRQ context on PREEMPT_RT kernels. (CVE-2022-48658)

    In the Linux kernel, the following vulnerability has been resolved: drm/i915/gem: Really move     i915_gem_context.link under ref protection i915_perf assumes that it can use the i915_gem_context     reference to protect its i915->gem.contexts.list iteration. However, this requires that we do not remove     the context from the list until after we drop the final reference and release the struct. If, as     currently, we remove the context from the list during context_close(), the link.next pointer may be     poisoned while we are holding the context reference and cause a GPF (CVE-2022-48662)
