Vulnerabilidades

In the Linux kernel, the following vulnerability has been resolved: pinctrl: at91: Fix possible out-of-boundary access at91_gpio_probe() doesn't check that given OF alias is not available or something went wrong when trying to get it. This might have consequences when accessing gpio_chips array with that value as an…

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix WARN() in get_bpf_raw_tp_regs syzkaller reported an issue: Tracepoint like trace_mmap_lock_acquire_returned may cause nested call as the corner case show above, which will be resolved with more general method in the future. As a result,…

In the Linux kernel, the following vulnerability has been resolved: kernfs: Relax constraint in draining guard The active reference lifecycle provides the break/unbreak mechanism but the active reference is not truly active after unbreak -- callers don't use it afterwards but it's important for proper pairing of…

In the Linux kernel, the following vulnerability has been resolved: bpf: Avoid __bpf_prog_ret0_warn when jit fails syzkaller reported an issue: When creating bpf program, 'fp->jit_requested' depends on bpf_jit_enable. This issue is triggered because of CONFIG_BPF_JIT_ALWAYS_ON is not set and bpf_jit_enable is set to…

In the Linux kernel, the following vulnerability has been resolved: mtd: nand: ecc-mxic: Fix use of uninitialized variable ret If ctx->steps is zero, the loop processing ECC steps is skipped, and the variable ret remains uninitialized. It is later checked and returned, which leads to undefined behavior and may cause…

In the Linux kernel, the following vulnerability has been resolved: phy: qcom-qmp-usb: Fix an NULL vs IS_ERR() bug The qmp_usb_iomap() helper function currently returns the raw result of devm_ioremap() for non-exclusive mappings. Since devm_ioremap() may return a NULL pointer and the caller only checks error pointers…

In the Linux kernel, the following vulnerability has been resolved: net: tipc: fix refcount warning in tipc_aead_encrypt syzbot reported a refcount warning [1] caused by calling get_net() on a network namespace that is being destroyed (refcount=0). This happens when a TIPC discovery timer fires during network…

In the Linux kernel, the following vulnerability has been resolved: bcache: fix NULL pointer in cache_set_flush() 1. LINE#1794 - LINE#1887 is some codes about function of bch_cache_set_alloc(). 2. LINE#2078 - LINE#2142 is some codes about function of register_cache_set(). 3. register_cache_set() will call…

In the Linux kernel, the following vulnerability has been resolved: tty: serial: uartlite: register uart driver in init When two instances of uart devices are probing, a concurrency race can occur. If one thread calls uart_register_driver function, which first allocates and assigns memory to 'uart_state' member of…

In the Linux kernel, the following vulnerability has been resolved: btrfs: handle csum tree error with rescue=ibadroots correctly [BUG] There is syzbot based reproducer that can crash the kernel, with the following call trace: (With some debug output added) [CAUSE] Firstly the fs has a corrupted csum tree root, thus…

In the Linux kernel, the following vulnerability has been resolved: ASoC: codecs: wcd9335: Fix missing free of regulator supplies Driver gets and enables all regulator supplies in probe path (wcd9335_parse_dt() and wcd9335_power_on_reset()), but does not cleanup in final error paths and in unbind (missing remove()…

In the Linux kernel, the following vulnerability has been resolved: s390/pkey: Prevent overflow in size calculation for memdup_user() Number of apqn target list entries contained in 'nr_apqns' variable is determined by userspace via an ioctl call so the result of the product in calculation of size passed to…

In the Linux kernel, the following vulnerability has been resolved: atm: clip: prevent NULL deref in clip_push() Blamed commit missed that vcc_destroy_socket() calls clip_push() with a NULL skb. If clip_devs is NULL, clip_push() then crashes when reading skb->truesize.

In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Fix out-of-bounds read in snd_usb_get_audioformat_uac3() In snd_usb_get_audioformat_uac3(), the length value returned from snd_usb_ctl_msg() is used directly for memory allocation without validation. This length is controlled by the…

In the Linux kernel, the following vulnerability has been resolved: atm: Release atm_dev_mutex after removing procfs in atm_dev_deregister(). syzbot reported a warning below during atm_dev_register(). [0] Before creating a new device and procfs/sysfs for it, atm_dev_register() looks up a duplicated device by…

In the Linux kernel, the following vulnerability has been resolved: scsi: megaraid_sas: Fix invalid node index On a system with DRAM interleave enabled, out-of-bound access is detected: Fix it accordingly.

Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals. When reading a config value, Git strips any trailing carriage return and line feed (CRLF). When writing a config entry, values with a trailing CR are…

In the Linux kernel, the following vulnerability has been resolved: media: platform: exynos4-is: Add hardware sync wait to fimc_is_hw_change_mode() In fimc_is_hw_change_mode(), the function changes camera modes without waiting for hardware completion, risking corrupted data or system hangs if subsequent operations…

In the Linux kernel, the following vulnerability has been resolved: af_unix: Don't leave consecutive consumed OOB skbs. Jann Horn reported a use-after-free in unix_stream_read_generic(). The following sequences reproduce the issue: Even though a user reads OOB data, the skb holding the data stays on the recv queue to…

In the Linux kernel, the following vulnerability has been resolved: nfsd: Initialize ssc before laundromat_work to prevent NULL dereference In nfs4_state_start_net(), laundromat_work may access nfsd_ssc through nfs4_laundromat -> nfsd4_ssc_expire_umount. If nfsd_ssc isn't initialized, this can cause NULL pointer…

In the Linux kernel, the following vulnerability has been resolved: jfs: validate AG parameters in dbMount() to prevent crashes Validate db_agheight, db_agwidth, and db_agstart in dbMount to catch corrupted metadata early and avoid undefined behavior in dbAllocAG. Limits are derived from L2LPERCTL, LPERCTL/MAXAG, and…

In the Linux kernel, the following vulnerability has been resolved: media: cxusb: no longer judge rbuf when the write fails syzbot reported a uninit-value in cxusb_i2c_xfer. [1] Only when the write operation of usb_bulk_msg() in dvb_usb_generic_rw() succeeds and rlen is greater than 0, the read operation of…

In the Linux kernel, the following vulnerability has been resolved: media: vidtv: Terminating the subsequent process of initialization failure syzbot reported a slab-use-after-free Read in vidtv_mux_init. [1] After PSI initialization fails, the si member is accessed again, resulting in this uaf. After si…

In the Linux kernel, the following vulnerability has been resolved: media: vivid: Change the siize of the composing syzkaller found a bug: The composition size cannot be larger than the size of fmt_cap_rect. So execute v4l2_rect_map_inside() even if has_compose_cap == 0.

In the Linux kernel, the following vulnerability has been resolved: media: imx-jpeg: Cleanup after an allocation error When allocation failures are not cleaned up by the driver, further allocation errors will be false-positives, which will cause buffers to remain uninitialized and cause NULL pointer dereferences.…
