GHSA-98X5-562F-MWVP

Vulnerability from github – Published: 2024-02-23 15:30 – Updated: 2024-04-19 21:31
VLAI
Details

In the Linux kernel, the following vulnerability has been resolved:

media: v4l: async: Fix duplicated list deletion

The list deletion call dropped here is already called from the helper function in the line before. Having a second list_del() call results in either a warning (with CONFIG_DEBUG_LIST=y):

list_del corruption, c46c8198->next is LIST_POISON1 (00000100)

If CONFIG_DEBUG_LIST is disabled the operation results in a kernel error due to NULL pointer dereference.

Vulnerability from github – Published: 2022-05-24 16:49 – Updated: 2024-04-04 01:12
VLAI
Details

A vulnerability in Cisco SIP IP Phone Software for Cisco IP Phone 7800 Series and 8800 Series could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected phone. The vulnerability is due to insufficient validation of input Session Initiation Protocol (SIP) packets. An attacker could exploit this vulnerability by altering the SIP replies that are sent to the affected phone during the registration process. A successful exploit could allow the attacker to cause the phone to reboot and not complete the registration process.

GHSA-99H3-VVC6-H7GH

Vulnerability from github – Published: 2024-03-11 18:31 – Updated: 2024-12-12 18:30
VLAI
Details

In the Linux kernel, the following vulnerability has been resolved:

net/mlx5e: Fix peer flow lists handling

The cited change refactored mlx5e_tc_del_fdb_peer_flow() to only clear DUP flag when list of peer flows has become empty. However, if any concurrent user holds a reference to a peer flow (for example, the neighbor update workqueue task is updating peer flow's parent encap entry concurrently), then the flow will not be removed from the peer list and, consecutively, DUP flag will remain set. Since mlx5e_tc_del_fdb_peers_flow() calls mlx5e_tc_del_fdb_peer_flow() for every possible peer index the algorithm will try to remove the flow from eswitch instances that it has never peered with causing either NULL pointer dereference when trying to remove the flow peer list head of peer_index that was never initialized or a warning if the list debug config is enabled[0].

Fix the issue by always removing the peer flow from the list even when not releasing the last reference to it.

However, if any concurrent\nuser holds a reference to a peer flow (for example, the neighbor update\nworkqueue task is updating peer flow\u0027s parent encap entry concurrently),\nthen the flow will not be removed from the peer list and, consecutively,\nDUP flag will remain set. Since mlx5e_tc_del_fdb_peers_flow() calls\nmlx5e_tc_del_fdb_peer_flow() for every possible peer index the algorithm\nwill try to remove the flow from eswitch instances that it has never peered\nwith causing either NULL pointer dereference when trying to remove the flow\npeer list head of peer_index that was never initialized or a warning if the\nlist debug config is enabled[0].\n\nFix the issue by always removing the peer flow from the list even when not\nreleasing the last reference to it.\n\n[0]:\n\n[ 3102.985806] ------------[ cut here ]------------\n[ 3102.986223] list_del corruption, ffff888139110698-\u003enext is NULL\n[ 3102.986757] WARNING: CPU: 2 PID: 22109 at lib/list_debug.c:53 __list_del_entry_valid_or_report+0x4f/0xc0\n[ 3102.987561] Modules linked in: act_ct nf_flow_table bonding act_tunnel_key act_mirred act_skbedit vxlan cls_matchall nfnetlink_cttimeout act_gact cls_flower sch_ingress mlx5_vdpa vringh vhost_iotlb vdpa openvswitch nsh xt_MASQUERADE nf_conntrack_netlink nfnetlink iptable_nat xt_addrtype xt_conntrack nf_nat br_netfilter rpcsec_gss_krb5 auth_rpcg\nss oid_registry overlay rpcrdma rdma_ucm ib_iser libiscsi scsi_transport_iscsi ib_umad rdma_cm ib_ipoib iw_cm ib_cm mlx5_ib ib_uverbs ib_core mlx5_core [last unloaded: bonding]\n[ 3102.991113] CPU: 2 PID: 22109 Comm: revalidator28 Not tainted 6.6.0-rc6+ #3\n[ 3102.991695] Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.13.0-0-gf21b5a4aeb02-prebuilt.qemu.org 04/01/2014\n[ 3102.992605] RIP: 0010:__list_del_entry_valid_or_report+0x4f/0xc0\n[ 3102.993122] Code: 39 c2 74 56 48 8b 32 48 39 fe 75 62 48 8b 51 08 48 39 f2 75 73 b8 01 00 00 00 c3 48 89 fe 48 c7 c7 48 fd 0a 82 e8 41 0b ad ff \u003c0f\u003e 0b 31 c0 c3 48 89 fe 48 c7 c7 70 fd 0a 82 e8 2d 0b ad ff 0f 0b\n[ 3102.994615] RSP: 0018:ffff8881383e7710 EFLAGS: 00010286\n[ 3102.995078] RAX: 0000000000000000 RBX: 0000000000000002 RCX: 0000000000000000\n[ 3102.995670] RDX: 0000000000000001 RSI: ffff88885f89b640 RDI: ffff88885f89b640\n[ 3102.997188] DEL flow 00000000be367878 on port 0\n[ 3102.998594] RBP: dead000000000122 R08: 0000000000000000 R09: c0000000ffffdfff\n[ 3102.999604] R10: 0000000000000008 R11: ffff8881383e7598 R12: dead000000000100\n[ 3103.000198] R13: 0000000000000002 R14: ffff888139110000 R15: ffff888101901240\n[ 3103.000790] FS:  00007f424cde4700(0000) GS:ffff88885f880000(0000) knlGS:0000000000000000\n[ 3103.001486] CS:  0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n[ 3103.001986] CR2: 00007fd42e8dcb70 CR3: 000000011e68a003 CR4: 0000000000370ea0\n[ 3103.002596] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000\n[ 3103.003190] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400\n[ 3103.003787] Call Trace:\n[ 3103.004055]  \u003cTASK\u003e\n[ 3103.004297]  ? __warn+0x7d/0x130\n[ 3103.004623]  ? __list_del_entry_valid_or_report+0x4f/0xc0\n[ 3103.005094]  ? report_bug+0xf1/0x1c0\n[ 3103.005439]  ? console_unlock+0x4a/0xd0\n[ 3103.005806]  ? handle_bug+0x3f/0x70\n[ 3103.006149]  ? exc_invalid_op+0x13/0x60\n[ 3103.006531]  ? asm_exc_invalid_op+0x16/0x20\n[ 3103.007430]  ? __list_del_entry_valid_or_report+0x4f/0xc0\n[ 3103.007910]  mlx5e_tc_del_fdb_peers_flow+0xcf/0x240 [mlx5_core]\n[ 3103.008463]  mlx5e_tc_del_flow+0x46/0x270 [mlx5_core]\n[ 3103.008944]  mlx5e_flow_put+0x26/0x50 [mlx5_core]\n[ 3103.009401]  mlx5e_delete_flower+0x25f/0x380 [mlx5_core]\n[ 3103.009901]  tc_setup_cb_destroy+0xab/0x180\n[ 3103.010292]  fl_hw_destroy_filter+0x99/0xc0 [cls_flower]\n[ 3103.010779]  __fl_delete+0x2d4/0x2f0 [cls_flower]\n[ 3103.0\n---truncated---",

In the Linux kernel, the following vulnerability has been resolved:

wifi: mt76: mt7925: prevent NULL vif dereference in mt7925_mac_write_txwi

Check for a NULL vif before accessing ieee80211_vif_is_mld(vif) to avoid a potential kernel panic in scenarios where vif might not be initialized.

Mitigation MIT-56
Implementation

For any pointers that could have been modified or provided from a function that can return NULL, check the pointer for NULL before use. When working with a multithreaded or otherwise asynchronous environment, ensure that proper locking APIs are used to lock before the check, and unlock when it has finished [REF-1484].

Mitigation
Requirements

Select a programming language that is not susceptible to these issues.

Mitigation
Implementation

Check the results of all functions that return a value and verify that the value is non-null before acting upon it.

Mitigation
Architecture and Design

Identify all variables and data stores that receive information from external sources, and apply input validation to make sure that they are only initialized to expected values.

Mitigation
Implementation

Explicitly initialize all variables and other data stores, either during declaration or just before the first usage.

No CAPEC attack patterns related to this CWE.
