CVE-2024-27011 2 Linux, Redhat 3 Linux Kernel, Enterprise Linux, Rhel Eus 2025-05-04 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: fix memleak in map from abort path The delete set command does not rely on the transaction object for element removal, therefore, a combination of delete element + delete set from the abort path could result in restoring twice the refcount of the mapping. Check for inactive element in the next generation for the delete element command in the abort path, skip restoring state if next generation bit has been already cleared. This is similar to the activate logic using the set walk iterator.

CVE-2024-26986 2 Fedoraproject, Linux 2 Fedora, Linux Kernel 2025-05-04 5.5 Medium

CVE-2024-26912 1 Linux 1 Linux Kernel 2025-05-04 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: drm/nouveau: fix several DMA buffer leaks Nouveau manages GSP-RM DMA buffers with nvkm_gsp_mem objects. Several of these buffers are never dealloced. Some of them can be deallocated right after GSP-RM is initialized, but the rest need to stay until the driver unloads. Also futher bullet-proof these objects by poisoning the buffer and clearing the nvkm_gsp_mem object when it is deallocated. Poisoning the buffer should trigger an error (or crash) from GSP-RM if it tries to access the buffer after we've deallocated it, because we were wrong about when it is safe to deallocate. Finally, change the mem->size field to a size_t because that's the same type that dma_alloc_coherent expects.

CVE-2024-26860 1 Linux 1 Linux Kernel 2025-05-04 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: dm-integrity: fix a memory leak when rechecking the data Memory for the "checksums" pointer will leak if the data is rechecked after checksum failure (because the associated kfree won't happen due to 'goto skip_io'). Fix this by freeing the checksums memory before recheck, and just use the "checksum_onstack" memory for storing checksum during recheck.

In the Linux kernel, the following vulnerability has been resolved: x86/kexec: fix memory leak of elf header buffer This is reported by kmemleak detector: unreferenced object 0xffffc900002a9000 (size 4096): comm "kexec", pid 14950, jiffies 4295110793 (age 373.951s) hex dump (first 32 bytes): 7f 45 4c 46 02 01 01 00 00 00 00 00 00 00 00 00 .ELF............ 04 00 3e 00 01 00 00 00 00 00 00 00 00 00 00 00 ..>............. backtrace: [<0000000016a8ef9f>] __vmalloc_node_range+0x101/0x170 [<000000002b66b6c0>] __vmalloc_node+0xb4/0x160 [<00000000ad40107d>] crash_prepare_elf64_headers+0x8e/0xcd0 [<0000000019afff23>] crash_load_segments+0x260/0x470 [<0000000019ebe95c>] bzImage64_load+0x814/0xad0 [<0000000093e16b05>] arch_kexec_kernel_image_load+0x1be/0x2a0 [<000000009ef2fc88>] kimage_file_alloc_init+0x2ec/0x5a0 [<0000000038f5a97a>] __do_sys_kexec_file_load+0x28d/0x530 [<0000000087c19992>] do_syscall_64+0x3b/0x90 [<0000000066e063a4>] entry_SYSCALL_64_after_hwframe+0x44/0xae In crash_prepare_elf64_headers(), a buffer is allocated via vmalloc() to store elf headers. While it's not freed back to system correctly when kdump kernel is reloaded or unloaded. Then memory leak is caused. Fix it by introducing x86 specific function arch_kimage_file_post_load_cleanup(), and freeing the buffer there. And also remove the incorrect elf header buffer freeing code. Before calling arch specific kexec_file loading function, the image instance has been initialized. So 'image->elf_headers' must be NULL. It doesn't make sense to free the elf header buffer in the place. Three different people have reported three bugs about the memory leak on x86_64 inside Redhat.
CVE-2022-49539 1 Redhat 1 Enterprise Linux 2025-05-04 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: rtw89: ser: fix CAM leaks occurring in L2 reset The CAM, meaning address CAM and bssid CAM here, will get leaks during SER (system error recover) L2 reset process and ieee80211_restart_hw() which is called by L2 reset process eventually. The normal flow would be like -> add interface (acquire 1) -> enter ips (release 1) -> leave ips (acquire 1) -> connection (occupy 1) <(A) 1 leak after L2 reset if non-sec connection> The ieee80211_restart_hw() flow (under connection) -> ieee80211 reconfig -> add interface (acquire 1) -> leave ips (acquire 1) -> connection (occupy (A) + 2) <(B) 1 more leak> Originally, CAM is released before HW restart only if connection is under security. Now, release CAM whatever connection it is to fix leak in (A). OTOH, check if CAM is already valid to avoid acquiring multiple times to fix (B). Besides, if AP mode, release address CAM of all stations before HW restart.
CVE-2022-49442 1 Redhat 1 Enterprise Linux 2025-05-04 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: drivers/base/node.c: fix compaction sysfs file leak Compaction sysfs file is created via compaction_register_node in register_node. But we forgot to remove it in unregister_node. Thus compaction sysfs file is leaked. Using compaction_unregister_node to fix this issue.
CVE-2022-49219 1 Linux 1 Linux Kernel 2025-05-04 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: vfio/pci: fix memory leak during D3hot to D0 transition If 'vfio_pci_core_device::needs_pm_restore' is set (PCI device does not have No_Soft_Reset bit set in its PMCSR config register), then the current PCI state will be saved locally in 'vfio_pci_core_device::pm_save' during D0->D3hot transition and same will be restored back during D3hot->D0 transition. For saving the PCI state locally, pci_store_saved_state() is being used and the pci_load_and_free_saved_state() will free the allocated memory. But for reset related IOCTLs, vfio driver calls PCI reset-related API's which will internally change the PCI power state back to D0. So, when the guest resumes, then it will get the current state as D0 and it will skip the call to vfio_pci_set_power_state() for changing the power state to D0 explicitly. In this case, the memory pointed by 'pm_save' will never be freed. In a malicious sequence, the state changing to D3hot followed by VFIO_DEVICE_RESET/VFIO_DEVICE_PCI_HOT_RESET can be run in a loop and it can cause an OOM situation. This patch frees the earlier allocated memory first before overwriting 'pm_save' to prevent the mentioned memory leak.
CVE-2022-49190 1 Linux 1 Linux Kernel 2025-05-04 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: kernel/resource: fix kfree() of bootmem memory again Since commit ebff7d8f270d ("mem hotunplug: fix kfree() of bootmem memory"), we could get a resource allocated during boot via alloc_resource(). And it's required to release the resource using free_resource(). Howerver, many people use kfree directly which will result in kernel BUG. In order to fix this without fixing every call site, just leak a couple of bytes in such corner case.
