|---|---|---|---|
| 2024-07-10 | CVE-2024-39493 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: crypto: qat - Fix ADF_DEV_RESET_SYNC memory leak Using completion_done to determine whether the caller has gone away only works after a complete call. | 5.5 |
| 2024-07-05 | CVE-2024-39472 | Allocation of Resources Without Limits or Throttling vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: xfs: fix log recovery buffer allocation for the legacy h_size fixup Commit a70f9fe52daa ("xfs: detect and handle invalid iclog size set by mkfs") added a fixup for incorrect h_size values used for the initial umount record in old xfsprogs versions. | 5.5 |
| 2024-07-05 | CVE-2024-39473 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ASoC: SOF: ipc4-topology: Fix input format query of process modules without base extension If a process module does not have base config extension then the same format applies to all of it's inputs and the process->base_config_ext is NULL, causing NULL dereference when specifically crafted topology and sequences used. | 5.5 |
| 2024-07-05 | CVE-2024-39474 | Allocation of Resources Without Limits or Throttling vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: mm/vmalloc: fix vmalloc which may return null if called with __GFP_NOFAIL commit a421ef303008 ("mm: allow !GFP_KERNEL allocations for kvmalloc") includes support for __GFP_NOFAIL, but it presents a conflict with commit dd544141b9eb ("vmalloc: back off when the current task is OOM-killed"). | 5.5 |
| 2024-07-05 | CVE-2024-39475 | Divide By Zero vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: fbdev: savage: Handle err return when savagefb_check_var failed The commit 04e5eac8f3ab("fbdev: savage: Error out if pixclock equals zero") checks the value of pixclock to avoid divide-by-zero error. | 5.5 |
| 2024-07-05 | CVE-2024-39476 | Improper Locking vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: md/raid5: fix deadlock that raid5d() wait for itself to clear MD_SB_CHANGE_PENDING Xiao reported that lvm2 test lvconvert-raid-takeover.sh can hang with small possibility, the root cause is exactly the same as commit bed9e27baf52 ("Revert "md/raid5: Wait for MD_SB_CHANGE_PENDING in raid5d"") However, Dan reported another hang after that, and junxiao investigated the problem and found out that this is caused by plugged bio can't issue from raid5d(). Current implementation in raid5d() has a weird dependence: 1) md_check_recovery() from raid5d() must hold 'reconfig_mutex' to clear MD_SB_CHANGE_PENDING; 2) raid5d() handles IO in a deadloop, until all IO are issued; 3) IO from raid5d() must wait for MD_SB_CHANGE_PENDING to be cleared; This behaviour is introduce before v2.6, and for consequence, if other context hold 'reconfig_mutex', and md_check_recovery() can't update super_block, then raid5d() will waste one cpu 100% by the deadloop, until 'reconfig_mutex' is released. Refer to the implementation from raid1 and raid10, fix this problem by skipping issue IO if MD_SB_CHANGE_PENDING is still set after md_check_recovery(), daemon thread will be woken up when 'reconfig_mutex' is released. | 5.5 |
| 2024-07-05 | CVE-2024-39477 | Allocation of Resources Without Limits or Throttling vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: mm/hugetlb: do not call vma_add_reservation upon ENOMEM sysbot reported a splat [1] on __unmap_hugepage_range(). | 5.5 |
| 2024-07-05 | CVE-2024-39478 | Allocation of Resources Without Limits or Throttling vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: crypto: starfive - Do not free stack buffer RSA text data uses variable length buffer allocated in software stack. Calling kfree on it causes undefined behaviour in subsequent operations. | 5.5 |
| 2024-07-05 | CVE-2024-39481 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: media: mc: Fix graph walk in media_pipeline_start The graph walk tries to follow all links, even if they are not between pads. | 5.5 |
| 2024-07-05 | CVE-2024-39482 | Allocation of Resources Without Limits or Throttling vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: bcache: fix variable length array abuse in btree_iter btree_iter is used in two ways: either allocated on the stack with a fixed size MAX_BSETS, or from a mempool with a dynamic size based on the specific cache set. | 5.5 |
