hwmon: (coretemp) fix pci device refcount leak in nv1a_ram_new()
Summary
In the Linux kernel, the following vulnerability has been resolved:
hwmon: (coretemp) fix pci device refcount leak in nv1a_ram_new()
As comment of pci_get_domain_bus_and_slot() says, it returns
a pci device with refcount increment, when finish using it,
the caller must decrement the reference count by calling
pci_dev_put(). So call it after using to avoid refcount leak.

Title
mm: call the security_mmap_file() LSM hook in remap_file_pages()
Summary
In the Linux kernel, the following vulnerability has been resolved:
mm: call the security_mmap_file() LSM hook in remap_file_pages()
The remap_file_pages syscall handler calls do_mmap() directly, which
doesn't contain the LSM security check. And if the process has called
personality(READ_IMPLIES_EXEC) before and remap_file_pages() is called for
RW pages, this will actually result in remapping the pages to RWX,
bypassing a W^X policy enforced by SELinux.
So we should check prot by security_mmap_file LSM hook in the
remap_file_pages syscall handler before do_mmap() is called. Otherwise, it
potentially permits an attacker to bypass a W^X policy enforced by
SELinux.
The bypass is similar to CVE-2016-10044, which bypass the same thing via
AIO and can be found in [1].
The PoC:
$ cat > test.c
int main(void) {
size_t pagesz = sysconf(_SC_PAGE_SIZE);
int mfd = syscall(SYS_memfd_create, "test", 0);
const char *buf = mmap(NULL, 4 * pagesz, PROT_READ | PROT_WRITE,
MAP_SHARED, mfd, 0);
unsigned int old = syscall(SYS_personality, 0xffffffff);
syscall(SYS_personality, READ_IMPLIES_EXEC | old);
syscall(SYS_remap_file_pages, buf, pagesz, 0, 2, 0);
syscall(SYS_personality, old);
// show the RWX page exists even if W^X policy is enforced
int fd = open("/proc/self/maps", O_RDONLY);
unsigned char buf2[1024];
while (1) {
int ret = read(fd, buf2, 1024);
if (ret <= 0) break;
write(1, buf2, ret);
}
close(fd);
}
$ gcc test.c -o test
$ ./test | grep rwx

"value": "AV:L - The bypass is performed entirely through local syscalls (`memfd_create`/`mmap`/`personality`/`remap_file_pages`) operating on the calling task\u0027s own `mm_struct`. There is no network- or adjacent-reachable path into `SYSCALL_DEFINE5(remap_file_pages)`.\nAC:L - The commit\u0027s PoC is fully deterministic \u2014 no race, no heap grooming, no memory-layout dependency \u2014 and the attacker controls every input. SELinux in enforcing mode with a W^X policy is the default on Android, RHEL/CentOS and Fedora, so the required configuration is common rather than rare.\nPR:L - Any unprivileged local process can do this: `personality()` in `kernel/exec_domain.c:38` performs no capability check, and `remap_file_pages` has no privilege gate whatsoever. No user namespace trick is even needed.\nUI:N - The attacking process performs the entire sequence against its own address space in one self-contained program. No victim action, file open, or mount is required.\nS:U - The vulnerable code and the impacted resource are both governed by the kernel\u0027s own security authority, and the resulting RWX mapping lives in the attacker\u0027s own address space. This is a MAC-policy/mitigation bypass, not a VM, IOMMU, or hypervisor boundary crossing.\nC:H - Defeating W^X lets an attacker inject and run arbitrary code inside an SELinux-confined domain, which yields unrestricted read of all data and credentials that domain can reach (e.g. a confined network daemon\u0027s keys or an Android system service\u0027s data). The skipped hook also drops the `file { read/write/map }` re-validation entirely.\nI:H - The whole purpose of the SELinux `execmem`/`file execute` checks is to stop a memory-write primitive from becoming code execution; bypassing them gives the attacker arbitrary code execution in the confined domain and full modification of anything it controls. This is the same integrity impact as the analogous AIO W^X bypass, CVE-2016-10044.\nA:H - Arbitrary code execution inside a confined domain lets the attacker fully disrupt or terminate the affected service, and the mitigation bypass is the enabling step that completes exploit chains whose payloads can crash or hang the system. Following the higher-severity convention where the ceiling of the bypass is complete compromise of the confined component."

Title
netfilter: ipset: add missing range check in bitmap_ip_uadt
Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: ipset: add missing range check in bitmap_ip_uadt
When tb[IPSET_ATTR_IP_TO] is not present but tb[IPSET_ATTR_CIDR] exists,
the values of ip and ip_to are slightly swapped. Therefore, the range check
for ip should be done later, but this part is missing and it seems that the
vulnerability occurs.
So we should add missing range checks and remove unnecessary range checks.
Severity
7.8 (High)

Address the bug by moving from devm_kmalloc() to devm_add_action() and
kvmalloc() and devm_add_action().

Title
soc: qcom: socinfo: Avoid out of bounds read of serial number
Summary
In the Linux kernel, the following vulnerability has been resolved:
soc: qcom: socinfo: Avoid out of bounds read of serial number
On MSM8916 devices, the serial number exposed in sysfs is constant and does
not change across individual devices. It's always:
db410c:/sys/devices/soc0$ cat serial_number
2644893864
The firmware used on MSM8916 exposes SOCINFO_VERSION(0, 8), which does not
have support for the serial_num field in the socinfo struct. There is an
existing check to avoid exposing the serial number in that case, but it's
not correct: When checking the item_size returned by SMEM, we need to make
sure the *end* of the serial_num is within bounds, instead of comparing
with the *start* offset. The serial_number currently exposed on MSM8916
devices is just an out of bounds read of whatever comes after the socinfo
struct in SMEM.
Fix this by changing offsetof() to offsetofend(), so that the size of the
field is also taken into account.
Severity
No CVSS data available.

Title
rtc: pcf85063: fix potential OOB write in PCF85063 NVMEM read
Summary
In the Linux kernel, the following vulnerability has been resolved:
rtc: pcf85063: fix potential OOB write in PCF85063 NVMEM read
The nvmem interface supports variable buffer sizes, while the regmap
interface operates with fixed-size storage. If an nvmem client uses a
buffer size less than 4 bytes, regmap_read will write out of bounds
as it expects the buffer to point at an unsigned int.
Fix this by using an intermediary unsigned int to hold the value.

Title
vsock: Keep the binding until socket destruction
Summary
In the Linux kernel, the following vulnerability has been resolved:
vsock: Keep the binding until socket destruction
Preserve sockets bindings; this includes both resulting from an explicit
bind() and those implicitly bound through autobind during connect().
Prevents socket unbinding during a transport reassignment, which fixes a
use-after-free:
1. vsock_create() (refcnt=1) calls vsock_insert_unbound() (refcnt=2)
2. transport->release() calls vsock_remove_bound() without checking if
sk was bound and moved to bound list (refcnt=1)
3. vsock_bind() assumes sk is in unbound list and before
__vsock_insert_bound(vsock_bound_sockets()) calls
__vsock_remove_bound() which does:
list_del_init(&vsk->bound_table); // nop
sock_put(&vsk->sk); // refcnt=0

Title
nvme-tcp: fix potential memory corruption in nvme_tcp_recv_pdu()
Summary
In the Linux kernel, the following vulnerability has been resolved:
nvme-tcp: fix potential memory corruption in nvme_tcp_recv_pdu()
nvme_tcp_recv_pdu() doesn't check the validity of the header length.
When header digests are enabled, a target might send a packet with an
invalid header length (e.g. 255), causing nvme_tcp_verify_hdgst()
to access memory outside the allocated area and cause memory corruptions
by overwriting it with the calculated digest.
Fix this by rejecting packets with an unexpected header length.

Title
iscsi_ibft: Fix UBSAN shift-out-of-bounds warning in ibft_attr_show_nic()
Summary
In the Linux kernel, the following vulnerability has been resolved:
iscsi_ibft: Fix UBSAN shift-out-of-bounds warning in ibft_attr_show_nic()
When performing an iSCSI boot using IPv6, iscsistart still reads the
/sys/firmware/ibft/ethernetX/subnet-mask entry. Since the IPv6 prefix
length is 64, this causes the shift exponent to become negative,
triggering a UBSAN warning. As the concept of a subnet mask does not
apply to IPv6, the value is set to ~0 to suppress the warning message.

Since the IPv6 prefix\nlength is 64, this causes the shift exponent to become negative,\ntriggering a UBSAN warning. As the concept of a subnet mask does not\napply to IPv6, the value is set to ~0 to suppress the warning message."
