| 2024-06-25 | CVE-2024-39463 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: 9p: add missing locking around taking dentry fid list Fix a use-after-free on dentry's d_fsdata fid list when a thread looks up a fid through dentry while another thread unlinks it: UAF thread: refcount_t: addition on 0; use-after-free. p9_fid_get linux/./include/net/9p/client.h:262 v9fs_fid_find+0x236/0x280 linux/fs/9p/fid.c:129 v9fs_fid_lookup_with_uid linux/fs/9p/fid.c:181 v9fs_fid_lookup+0xbf/0xc20 linux/fs/9p/fid.c:314 v9fs_vfs_getattr_dotl+0xf9/0x360 linux/fs/9p/vfs_inode_dotl.c:400 vfs_statx+0xdd/0x4d0 linux/fs/stat.c:248 Freed by: p9_fid_destroy (inlined) p9_client_clunk+0xb0/0xe0 linux/net/9p/client.c:1456 p9_fid_put linux/./include/net/9p/client.h:278 v9fs_dentry_release+0xb5/0x140 linux/fs/9p/vfs_dentry.c:55 v9fs_remove+0x38f/0x620 linux/fs/9p/vfs_inode.c:518 vfs_unlink+0x29a/0x810 linux/fs/namei.c:4335 The problem is that d_fsdata was not accessed under d_lock, because d_release() normally is only called once the dentry is otherwise no longer accessible but since we also call it explicitly in v9fs_remove that lock is required: move the hlist out of the dentry under lock then unref its fids once they are no longer accessible. | 7.8 |
| 2024-06-25 | CVE-2024-39466 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: thermal/drivers/qcom/lmh: Check for SCM availability at probe Up until now, the necessary scm availability check has not been performed, leading to possible null pointer dereferences (which did happen for me on RB1). Fix that. | 5.5 |
| 2024-06-25 | CVE-2024-39468 | Improper Locking vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: smb: client: fix deadlock in smb2_find_smb_tcon() Unlock cifs_tcp_ses_lock before calling cifs_put_smb_ses() to avoid such deadlock. | 5.5 |
| 2024-06-25 | CVE-2024-39471 | Out-of-bounds Read vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: add error handle to avoid out-of-bounds if the sdma_v4_0_irq_id_to_seq return -EINVAL, the process should be stop to avoid out-of-bounds read, so directly return -EINVAL. | 7.1 |
| 2024-06-24 | CVE-2024-38664 | Improper Locking vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm: zynqmp_dpsub: Always register bridge We must always register the DRM bridge, since zynqmp_dp_hpd_work_func calls drm_bridge_hpd_notify, which in turn expects hpd_mutex to be initialized. | 7.8 |
| 2024-06-24 | CVE-2024-39291 | Classic Buffer Overflow vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Fix buffer size in gfx_v9_4_3_init_ cp_compute_microcode() and rlc_microcode() The function gfx_v9_4_3_init_microcode in gfx_v9_4_3.c was generating about potential truncation of output when using the snprintf function. The issue was due to the size of the buffer 'ucode_prefix' being too small to accommodate the maximum possible length of the string being written into it. The string being written is "amdgpu/%s_mec.bin" or "amdgpu/%s_rlc.bin", where %s is replaced by the value of 'chip_name'. | 7.8 |
| 2024-06-21 | CVE-2024-36288 | Infinite Loop vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: SUNRPC: Fix loop termination condition in gss_free_in_token_pages() The in_token->pages[] array is not NULL terminated. | 5.5 |
| 2024-06-21 | CVE-2024-36477 | Out-of-bounds Read vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: tpm_tis_spi: Account for SPI header when allocating TPM SPI xfer buffer The TPM SPI transfer mechanism uses MAX_SPI_FRAMESIZE for computing the maximum transfer length and the size of the transfer buffer. | 7.8 |
| 2024-06-21 | CVE-2024-36481 | Improper Check for Unusual or Exceptional Conditions vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: tracing/probes: fix error check in parse_btf_field() btf_find_struct_member() might return NULL or an error via the ERR_PTR() macro. | 5.5 |
| 2024-06-21 | CVE-2024-36270 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: netfilter: tproxy: bail out if IP has been disabled on the device syzbot reports: general protection fault, probably for non-canonical address 0xdffffc0000000003: 0000 [#1] PREEMPT SMP KASAN PTI KASAN: null-ptr-deref in range [0x0000000000000018-0x000000000000001f] [..] RIP: 0010:nf_tproxy_laddr4+0xb7/0x340 net/ipv4/netfilter/nf_tproxy_ipv4.c:62 Call Trace: nft_tproxy_eval_v4 net/netfilter/nft_tproxy.c:56 [inline] nft_tproxy_eval+0xa9a/0x1a00 net/netfilter/nft_tproxy.c:168 __in_dev_get_rcu() can return NULL, so check for this. | 5.5 |
