| In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Fix a memory leak in an error path of qla2x00_process_els()
Commit 8c0eb596baa5 ("[SCSI] qla2xxx: Fix a memory leak in an error path of
qla2x00_process_els()"), intended to change:
bsg_job->request->msgcode == FC_BSG_HST_ELS_NOLOGIN
bsg_job->request->msgcode != FC_BSG_RPT_ELS
but changed it to:
bsg_job->request->msgcode == FC_BSG_RPT_ELS
instead.
Change the == to a != to avoid leaking the fcport structure or freeing
unallocated memory. |
| In the Linux kernel, the following vulnerability has been resolved:
io_uring: fix ltout double free on completion race
Always remove linked timeout on io_link_timeout_fn() from the master
request link list, otherwise we may get use-after-free when first
io_link_timeout_fn() puts linked timeout in the fail path, and then
will be found and put on master's free. |
| In the Linux kernel, the following vulnerability has been resolved:
iio: core: fix ioctl handlers removal
Currently ioctl handlers are removed twice. For the first time during
iio_device_unregister() then later on inside
iio_device_unregister_eventset() and iio_buffers_free_sysfs_and_mask().
Double free leads to kernel panic.
Fix this by not touching ioctl handlers list directly but rather
letting code responsible for registration call the matching cleanup
routine itself. |
| In the Linux kernel, the following vulnerability has been resolved:
dm rq: fix double free of blk_mq_tag_set in dev remove after table load fails
When loading a device-mapper table for a request-based mapped device,
and the allocation/initialization of the blk_mq_tag_set for the device
fails, a following device remove will cause a double free.
E.g. (dmesg):
device-mapper: core: Cannot initialize queue for request-based dm-mq mapped device
device-mapper: ioctl: unable to set up device queue for new table.
Unable to handle kernel pointer dereference in virtual kernel address space
Failing address: 0305e098835de000 TEID: 0305e098835de803

Kernel panic - not syncing: Fatal exception: panic_on_oops
When allocation/initialization of the blk_mq_tag_set fails in
dm_mq_init_request_queue(), it is uninitialized/freed, but the pointer
is not reset to NULL; so when dev_remove() later gets into
dm_mq_cleanup_mapped_device() it sees the pointer and tries to
uninitialize and free it again.
Fix this by setting the pointer to NULL in dm_mq_init_request_queue()
error-handling. Also set it to NULL in dm_mq_cleanup_mapped_device(). |
| In the Linux kernel, the following vulnerability has been resolved:
media: atomisp: Fix use after free in atomisp_alloc_css_stat_bufs()
The "s3a_buf" is freed along with all the other items on the
"asd->s3a_stats" list. It leads to a double free and a use after free. |
| Windows USB Print Driver Elevation of Privilege Vulnerability |
| Microsoft Excel Remote Code Execution Vulnerability |
| NTFS Elevation of Privilege Vulnerability |
| A double free vulnerability was found in QEMU virtio devices (virtio-gpu, virtio-serial-bus, virtio-crypto), where the mem_reentrancy_guard flag insufficiently protects against DMA reentrancy issues. This issue could allow a malicious privileged guest user to crash the QEMU process on the host, resulting in a denial of service or allow arbitrary code execution within the context of the QEMU process on the host. |
| diplib v3.0.0 is vulnerable to Double Free. |
| In audio, there is a possible memory corruption due to a logic error. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS07310571; Issue ID: ALPS07310571. |
| A double-free flaw was found in the Linux kernel’s NTFS3 subsystem in how a user triggers remount and umount simultaneously. This flaw allows a local user to crash or potentially escalate their privileges on the system. |
| An issue was discovered in libxml2 before 2.10.3. Certain invalid XML entity definitions can corrupt a hash table key, potentially leading to subsequent logic errors. In one case, a double-free can be provoked. |
| Adobe Bridge version 11.1.1 (and earlier) is affected by a double free vulnerability when parsing a crafted DCM file, which could result in arbitrary code execution in the context of the current user. This vulnerability requires user interaction to exploit. |
| UltraJSON is a fast JSON encoder and decoder written in pure C with bindings for Python 3.7+. In versions prior to 5.4.0 an error occurring while reallocating a buffer for string decoding can cause the buffer to get freed twice. Due to how UltraJSON uses the internal decoder, this double free is impossible to trigger from Python. This issue has been resolved in version 5.4.0 and all users should upgrade to UltraJSON 5.4.0. There are no known workarounds for this issue. |
| Rizin is a UNIX-like reverse engineering framework and command-line toolset. Versions 0.4.0 and prior are vulnerable to a double free in bobj.c:rz_bin_reloc_storage_free() when freeing relocations generated from qnx binary plugin. A user opening a malicious qnx binary could be affected by this vulnerability, allowing an attacker to execute code on the user's machine. Commit number a3d50c1ea185f3f642f2d8180715f82d98840784 contains a patch for this issue. |
| A vulnerability was found in drivers/cpufreq/qcom-cpufreq-hw.c in cpufreq subsystem in the Linux Kernel. This flaw, during device unbind will lead to double release problem leading to denial of service. |
| io_uring use work_flags to determine which identity need to grab from the calling process to make sure it is consistent with the calling process when executing IORING_OP. Some operations are missing some types, which can lead to incorrect reference counts which can then lead to a double free. We recommend upgrading the kernel past commit df3f3bb5059d20ef094d6b2f0256c4bf4127a859 |
| Double free vulnerability in MIT Kerberos 5 (aka krb5) allows attackers to have unspecified impact via vectors involving automatic deletion of security contexts on error. |
| An issue was discovered in Moxa SoftCMS versions prior to Version 1.6. A specially crafted URL request sent to the SoftCMS ASP Webserver can cause a double free condition on the server allowing an attacker to modify memory locations and possibly cause a denial of service or the execution of arbitrary code. |
