CVE-2022-50765 1 Linux 1 Linux Kernel 2026-04-15 N/A
In the Linux kernel, the following vulnerability has been resolved: RISC-V: kexec: Fix memory leak of elf header buffer This is reported by kmemleak detector: unreferenced object 0xff2000000403d000 (size 4096): comm "kexec", pid 146, jiffies 4294900633 (age 64.792s) hex dump (first 32 bytes): 7f 45 4c 46 02 01 01 00 00 00 00 00 00 00 00 00 .ELF............ 04 00 f3 00 01 00 00 00 00 00 00 00 00 00 00 00 ................ backtrace: [<00000000566ca97c>] kmemleak_vmalloc+0x3c/0xbe [<00000000979283d8>] __vmalloc_node_range+0x3ac/0x560 [<00000000b4b3712a>] __vmalloc_node+0x56/0x62 [<00000000854f75e2>] vzalloc+0x2c/0x34 [<00000000e9a00db9>] crash_prepare_elf64_headers+0x80/0x30c [<0000000067e8bf48>] elf_kexec_load+0x3e8/0x4ec [<0000000036548e09>] kexec_image_load_default+0x40/0x4c [<0000000079fbe1b4>] sys_kexec_file_load+0x1c4/0x322 [<0000000040c62c03>] ret_from_syscall+0x0/0x2 In elf_kexec_load(), a buffer is allocated via vzalloc() to store elf headers.

Fix it by freeing the buffer in arch_kimage_file_post_load_cleanup().
CVE-2022-50754 1 Linux 1 Linux Kernel 2026-04-15 N/A
In the Linux kernel, the following vulnerability has been resolved: apparmor: fix a memleak in multi_transaction_new() In multi_transaction_new(), the variable t is not freed or passed out on the failure of copy_from_user(t->data, buf, size), which could lead to a memleak. Fix this bug by adding a put_multi_transaction(t) in the error path.
CVE-2023-54031 1 Linux 1 Linux Kernel 2026-04-15 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: vdpa: Add queue index attr to vdpa_nl_policy for nlattr length check The vdpa_nl_policy structure is used to validate the nlattr when parsing the incoming nlmsg. It will ensure the attribute being described produces a valid nlattr pointer in info->attrs before entering into each handler in vdpa_nl_ops. That is to say, the missing part in vdpa_nl_policy may lead to illegal nlattr after parsing, which could lead to OOB read just like CVE-2023-3773. This patch adds the missing nla_policy for vdpa queue index attr to avoid such bugs.

CVE-2022-50749 1 Linux 1 Linux Kernel 2026-04-15 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: acct: fix potential integer overflow in encode_comp_t() The integer overflow is descripted with following codes: > 317 static comp_t encode_comp_t(u64 value) > 318 { > 319 int exp, rnd; ...... > 341 exp <<= MANTSIZE; > 342 exp += value; > 343 return exp; > 344 } Currently comp_t is defined as type of '__u16', but the variable 'exp' is type of 'int', so overflow would happen when variable 'exp' in line 343 is greater than 65535.

CVE-2025-68786 1 Linux 1 Linux Kernel 2026-04-15 N/A
In the Linux kernel, the following vulnerability has been resolved: ksmbd: skip lock-range check on equal size to avoid size==0 underflow When size equals the current i_size (including 0), the code used to call check_lock_range(filp, i_size, size - 1, WRITE), which computes `size - 1` and can underflow for size==0. Skip the equal case.
CVE-2022-50741 1 Linux 1 Linux Kernel 2026-04-15 N/A
In the Linux kernel, the following vulnerability has been resolved: media: imx-jpeg: Disable useless interrupt to avoid kernel panic There is a hardware bug that the interrupt STMBUF_HALF may be triggered after or when disable interrupt. It may led to unexpected kernel panic. And interrupt STMBUF_HALF and STMBUF_RTND have no other effect. So disable them and the unused interrupts. meanwhile clear the interrupt status when disable interrupt.

CVE-2025-68759 1 Linux 1 Linux Kernel 2026-04-15 N/A
In the Linux kernel, the following vulnerability has been resolved: wifi: rtl818x: Fix potential memory leaks in rtl8180_init_rx_ring() In rtl8180_init_rx_ring(), memory is allocated for skb packets and DMA allocations in a loop. When an allocation fails, the previously successful allocations are not freed on exit. Fix that by jumping to err_free_rings label on error, which calls rtl8180_free_rx_ring() to free the allocations. Remove the free of rx_ring in rtl8180_init_rx_ring() error path, and set the freed priv->rx_buf entry to null, to avoid double free.
CVE-2022-50721 1 Linux 1 Linux Kernel 2026-04-15 7.0 High
In the Linux kernel, the following vulnerability has been resolved: dmaengine: qcom-adm: fix wrong calling convention for prep_slave_sg The calling convention for pre_slave_sg is to return NULL on error and provide an error log to the system. Qcom-adm instead provide error pointer when an error occur. This indirectly cause kernel panic for example for the nandc driver that checks only if the pointer returned by device_prep_slave_sg is not NULL. Returning an error pointer makes nandc think the device_prep_slave_sg function correctly completed and makes the kernel panics later in the code. While nandc is the one that makes the kernel crash, it was pointed out that the real problem is qcom-adm not following calling convention for that function. To fix this, drop returning error pointer and return NULL with an error log.
CVE-2025-68763 1 Linux 1 Linux Kernel 2026-04-15 N/A
In the Linux kernel, the following vulnerability has been resolved: crypto: starfive - Correctly handle return of sg_nents_for_len The return value of sg_nents_for_len was assigned to an unsigned long in starfive_hash_digest, causing negative error codes to be converted to large positive integers. Add error checking for sg_nents_for_len and return immediately on failure to prevent potential buffer overflows.

We still need to store the updated queue settings in that case, and apply them later. Move the location of the queue params to within struct mt7996_vif_link.
CVE-2025-68737 1 Linux 1 Linux Kernel 2026-04-15 N/A
In the Linux kernel, the following vulnerability has been resolved: arm64/pageattr: Propagate return value from __change_memory_common The rodata=on security measure requires that any code path which does vmalloc -> set_memory_ro/set_memory_rox must protect the linear map alias too. Therefore, if such a call fails, we must abort set_memory_* and caller must take appropriate action; currently we are suppressing the error, and there is a real chance of such an error arising post commit a166563e7ec3 ("arm64: mm: support large block mapping when rodata=full"). Therefore, propagate any error to the caller.

In the Linux kernel, the following vulnerability has been resolved: ALSA: firewire-digi00x: prevent potential use after free This code was supposed to return an error code if init_stream() failed, but it instead freed dg00x->rx_stream and returned success. This potentially leads to a use after free.
CVE-2023-54093 1 Linux 1 Linux Kernel 2026-04-15 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: media: anysee: fix null-ptr-deref in anysee_master_xfer In anysee_master_xfer, msg is controlled by user. When msg[i].buf is null and msg[i].len is zero, former checks on msg[i].buf would be passed. Malicious data finally reach anysee_master_xfer. If accessing msg[i].buf[0] without sanity check, null ptr deref would happen. We add check on msg[i].len to prevent crash.

In the Linux kernel, the following vulnerability has been resolved: driver: soc: xilinx: use _safe loop iterator to avoid a use after free The hash_for_each_possible() loop dereferences "eve_data" to get the next item on the list. However the loop frees eve_data so it leads to a use after free. Use hash_for_each_possible_safe() instead.
